It was a you configuration problem so The next time be careful of this things, you'll earn a lot of time XD

Any plans on providing binary packages? I really don't want to compile Linux on a netbook

I suppose I need the initrd to decrypt the goddamn luks partition?

Does your resume work? I can get suspend to ram working with uswsusp (on lid-close, even!), but I can't get suspend to disk working. I realize that since we don't use an initrd, the wiki guide for adding the uresume hook in mkinitcpio.conf doesn't apply, but is there another way to do this?

Thanks.

(I wasn't able to find anything on the google page and the quote post is the only reference to {suspend,hibernate,resume} I was able to find in this thread..)

I don't use suspend and hibernate, so i can't help you..We have to wait a pielgrzym response...

btw, i've updated the kernel to 2.6.36 version

Zom · 2010-10-26 14:14:47

I know you have support for BFS, but how about BFQ?

dieghen89 · 2010-10-27 08:16:44

Hi Zom, i have used the BFS in the first period of live of kernel-netbook...Then the guys of the italian forum and me have decided that the performance gain was imperceptible so i removed the patch...

I dont know BFQ have you already tested it?

I'm running a patched kernel both on my workstation and on my laptop, with both BFS and BFQ. There's no noticable difference in regular performance from BFS/BFQ, but it quickly becomes noticable while using stuff like flash. Try starting a few flash-videos or games and try switching desktop or changing song.

BFS/BFQ pretty much makes the impact from flash unnoticable in the running system. Hell, you could be compiling stuff in the background and you wouldn't notice while playing music or browsing the web.

Both of these are present in kernel26-ck from AUR, you could give it a try and see what you think.

dieghen89 · 2010-10-29 10:20:35

Yes, i've tried the BFS some months ago and i haven't seen any changes, but i can give to this patch another chance if you say me that it works very well on high cpu load...With the next release i'll apply this patch...

twix · 2010-10-29 14:31:41

Hi, just updated the kernel, but i can't mount / as rw with kernel compiled from AUR. No problem with your precompiled package hosted on Google code.

and powertop advise me to set the CONFIG_INOTIFY to the kernel conf, in order to monitor passively folders and files instead of active monitoring (if you mind in a future version)

dieghen89 · 2010-10-29 14:36:04

Mmh now i'm uploading the -2 because the bradcom driver isn't updated...I've alsa added the BFS+BFQ scheduler as Zom has suggested...

Can you try to compile the new one, i've just ended to compile it and it works...Wait a few minutes and i'll upload the new packages on google code and aur...

dieghen89 · 2010-10-29 14:46:56

Updated!

@twix
I saw that powertop notice, but i haven't found that option...The only option with the similar name is:

diego@eeepc ~>sudo zcat /proc/config.gz | grep INOTIFY
Password: 
CONFIG_INOTIFY_USER=y

and it is already enabled..

Are you perhaps using fam or something similar?

'Cause FAM is outdated and replaced by gamin.

@dieghen89:
Thanks, I'll give it a spin when I have time.

twix · 2010-10-29 16:25:32

@ Zom : I just checked I just have gamin installed, fam is not present. And powertop indicate that this is only kernel-related. Maybe an deprecated parameter or renamed in newer kernels.

And thx for the binary, it save alot of time and work well !!

You can also add toshiba netbook as supported on your google code page (NB100 here)

I guess. Some things in powertop is a bit out of date, IIRC. You could try the git branch in AUR and see if there's any difference.

I have noticied a slight battery life improvement when idleing (4h -> 4h15) Maybe the BFS, i don't know

dieghen89 · 2010-10-30 07:35:57

It would be possible...With thw 2.6.36-1 i've enabled intel_ips...I think that this option stop the disk in idle...There is improvement of the battery life but my sistem freezes 2 time...If i have another freeze i try remove this option...

twix · 2010-10-30 14:33:11

Hum, i can't find docs about intel_ips, but maybe it's that , dk.

@zom I use already the git version, because yaourt makes it easy as hell

arch0r · 2010-10-31 07:14:48

was this kernel already tested with a btrfs root volume? i know that it doesn't support btrfs by default, but i recompiled it with the required modules but i always run into a kernel panic. i don't know what i'm doing wrong, maybe it's because of the root volume (/dev/sda2) is an encrypted lvm and i need an initrd image to map the btrfs volume?!

I don't know if legacy grub supports btrfs. You might need a ext2/3/4 /boot partition.

arch0r · 2010-10-31 08:44:03

i'm using grub2 on a ext4 partition. the stock kernel boots nicely, but the netbook-kernel runs into a panic

Strange indeed. Perhaps it built btrfs as a module and you'd need an initrd to boot?

dieghen89 · 2010-11-02 10:47:35

I never used btrfs, but i've read that an additional hook is needed --> need of initrd image...

@Zom
have you tried the BFS+BFQ kernel-netbook package? i have some random freeze and it isn't reactive as i expected...Maybe it can be the BFQ? I'm trying compile a package with only BFS to see the difference...

Zom · 2010-11-02 13:34:39

I did give the package a try, but only briefly since I ran into issues with suspend (Using uswsusp with pm-utils).

However, I'm currently running kernel26-ck and I've tried kernel26-pf. Both ran fine from what I gathered, though I had some issues with X, which I suspect was because I updated in the middle of the current xorg upgrade.
