ok add

session         required    pam_limits.so

to /etc/pam.d/su

logout *completely* then log back in and try it.

as for the kill it might be

 
sudo kill -9 `pidof jackd`

I *think* those are backticks not single quotes

Yeah man something is definitely wrong if you have to unselect RT to use a realtime kernel; defeats the purpose; using realtime kernel as (almost) normal kernel.

If no other kernel works, then it's to do with your system configuration. Follow above suggestions.

do you mean that qjackctl RT selection should be selected? If yes, that's how I run it. I select RT under settings.

ran ps aux after sudo kill -9 `pidof jackd`
still alive
/usr/bin/jackd -R -P89 -dalsa -dhw:0 -r48000 -p128 -n2 -m -Xseq

sudo kill `pidof jackd`
run ps aux
/usr/bin/jackd -R -P89 -dalsa -dhw:0 -r48000 -p128 -n2 -m -Xseq

Hi All,

Does anyone have or can tell me where to get a PKGBUILD for the 2.25.something-RT that was in AUR about a month ago. I just tried to run the current AUR rt kernel and it looked like it was going to boot but no luck. That 2.25.something kernel ran great on my machine but I did a clean install and when I went to get it, it was gone.

Any help would be greatly appreciated,
Arthur

funkmuscle · 2008-10-14 04:21:17

sorry dude. don't have it. I'm still going through jack and qjackctl hell here. I don't think the kernels have anything to do with it, I don't install from testing so I just do get why jackd can only be killed by rebooting.

Frabato · 2008-10-14 05:33:18

Hi Funkmuscle,

Yes, I wish I could help you but I don't have a functioning DAW myself. Jackd on your system is definitley not right. There are so many variables on linux that troubleshooting can be a lot of trouble. Let's hope for the best.

Arthur

btartsa · 2008-10-14 16:59:33

@Frabato & funkmuscle: All the kernel and rt patch sources are availiable...if it does not work roll it back. The rt PKGBUILD is designed so you can easily substitute sources. Hell I still think 2.6.22 was the best! Don't worry about being bleeding edge on a bleeding edge technology!

Back things up!

My current setup: 2.6.24-rt21, jackmp-svn, alsa 1.0.17, slim-pam, ardour-svn,irqbalance is working nicely.

@funkmuscle:

ps -e | grep jackd

su

kill -9 *whatever pid was returned above*

From first google result for "killing linux pids":

Is the process changing PID after your kill -9 command? Because if it does it means it is a new process. This usually happens with apps that are being watched by some other process that will respawn the dead process.
To kill such a process you first need to find out what are the means used to respawn it and act accordingly. A "ps axf" will show you the relationship between processes. If the preocess you try to kill is a child of other process then it is most likely that the parent is respawning the child. So you will need to kill that process first. Otherwise, kill -9 used as root is "invincible"

funkmuscle · 2008-10-14 18:46:56

ya know what guys, I've tried it all and nothing shut it off except this:
/usr/bin/jackd -R -P89 -dalsa -dhw:0 -r48000 -p128 -n2 -m -Xseq.... the Xseq at the end of the command. I removed and now all works well.
That is strange because I've always had that there. Somemust of changed in the latest RT kernel.... speaking of the latest..rt10 cannot be found..

I kinda liked the old 2.6.24-rt. That ran the best but now I can't find it. Will try to do as you mentioned btartsa to roll back.

Thanx again Gents.

thanx again guys..

Frabato · 2008-10-14 20:58:57

Thanks btartsa,

Yes, I've been going backwards. I had the 2.6.25.something from AUR working quite well a while back so I'm trying to build one now. I'm sure I'll hit on a winning combination soon.

Thanks Again,
Arthur

Frabato · 2008-10-15 05:29:44

Hi All,

I feel so powerful, I just got 2.6.24-rt21 working. I do have one major problem though, and it goes like this:

"Cannot access the hardware clock via any known method"

I'm assuming (maybe incorrectly) that it's something that I didn't enable in the kernel config.

Any clues anyone?

Arthur

markc · 2008-10-15 07:26:02

Excellent news. I guess this means that the 32 bit Skype application will now be able to work on a 64 bit installation directly with only 32 bit support libs for Skype itself, ie; not needing a 32 bit ALSA. Does this sound right?

Looks like rev 3001 could be gold for a "stable" kernel+alsa+jack suite?

From: Paul Davis <paul@linuxaudiosystems.com>
To: jack-devel@lists.jackaudio.org
Date: 2008-10-15 16:33:43

JACK svn as of rev 3001 now contains fixes from Torben Hohn that remove
the pointers-in-shared-memory problem that has been in JACK from the
beginning of its life. This means that a JACK server compiled as a 64
bit application can now support 32 bit clients and vice versa. The JACK
version has been bumped to 0.114.0. There is, as usual, no need to
recompile or relink existing applications in order to use this.

I would appreciate feedback on its operation, especially on 64 bit
machines (I only have a 32 bit machine to test with at present).

Assuming that this works OK for everyone, I will release 0.114.0 as the
penultimate release of JACK before 1.0 later this week.

Not sure whats causing that. Search the forums for "Cannot access the hardware clock via any known method" and maybe something rings a bell for you?

There was also a bug report on this here:

http://bugs.archlinux.org/task/9636

Also a bug report for ubuntu...

I read them all and learned...well....nothing. Maybe you see something?

One idea: Check to see if you have any important .pacnew files. Maybe one for rc.conf? Are you dual booting windows?

UPDATE: OK I'm doing some serious digging here and should have this solved soon(hope).

If anyone wants to play along here's a few places to start:

I am assuming that's what you face when you use the new (?) RTC system, on which I was asking opinions for earlier on. Have you tried to modprobe rtc_cmos? Most of the time that solves it; load it automatically via rc.conf.

If not, follow the steps above in my post regarding kernels to enable the older RTC.

markc: Yep, sounds good for that.

Frabato · 2008-10-23 15:53:50

Hi All,

I built the new AUR kernel last night and the build went fine but jack does not want to start:

JACK compiled with POSIX SHM support.
cannot use real-time scheduling (FIFO at priority 10) [for thread 914319088, from thread 914319088] (1: Operation not permitted)
cannot create engine
01:13:02.068 JACK was stopped successfully.
01:13:02.069 Post-shutdown script...
01:13:02.069 killall jackd
jackd: no process killed
01:13:02.491 Post-shutdown script terminated with exit status=256.
01:13:04.190 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info

Looks like the same thing that funkmuscle got. Does anyone have a cure?

Arthur

funkmuscle · 2008-10-23 17:37:43

I went back to an earlier kernel. yeah, jack never started. I never tried rt11, it was rt9.

Frabato · 2008-10-23 22:06:05

Hi All,

With the new AUR kenel I shut the computer down and restarted and lots of stuff came up. I hope this bit is relevant.

Note: sirq-timer/3[45] exited with preempt_count2.

Thanks,
Arthur

schivmeister · 2008-10-24 20:18:04

Ok..looks like the RTC is a culprit. I'm updating it to use standard kernel's RTC, so please help test that one as it is (big thanks to all of you; it takes a very long time to build). If that goes well then we can come to a conlusion on the RTC system, so we can then roll out a stable kernel series (or someone can do it now - take the 2.6.24).

Frabato · 2008-10-25 03:45:59

Hi,

I'll test the new kernel tonight or tomorrow. I'd like to know what version of jack-audio-connection-kit people are running. I think that I had weird problems with my last install.
I got ths:

cannot use real-time scheduling (FIFO at priority 10) [for thread 914319088, from thread 914319088] (1: Operation not permitted)

with the AUR kernel and from the 2.6.26.5_rt9 google code kernel. I've had some interesting issues with permissions. What should the permissions be on the home folder?
I just did a clean install with openbox and not much else so I'll try the new kernel.

Thanks,
Arthur

Frabato · 2008-10-25 04:56:08

Hi schivmeister,

Is the new kernel in AUR yet? I just built the AUR kernel and got the same error message. It looks like the same kernel. Not a big deal, I have a 2.4 ghz quad core, down to the kitchen for a nibble and when you come back the compiling is all done. Keep me posted.

Thanks,
Arthur

Hi All,

I'm still trying to find a RT kernel that works on my machine. I just built 2.6.24.7 rt21 and it built just fine and it boots just fine but I still get:
cannot use real-time scheduling (FIFO at priority 10) [for thread -496426336, from thread -496426336] (1: Operation not permitted)
The only clue I have is that the regular kernel loads bmpanel at startup but the RT kernel does not. Running it from the terminal, I get:
[a@Astudio ~]$ bmpanel
starting bmpanel with theme: native
failed to create timer fd

does this mean something to anyone?

Thanks,
Arthur

hey Harv,
I have no idea what any of that stuff means.
