snd-hda-intel error

Since last kernel upgrade (2.6.38.4-1) I have no sound.  Running alsaconf seems to go well, but still no sound.
modprobe snd-hda-intel gives the error "Unknown symbol in a module, or unknown parameter.
dmesg | grep hda  tells (7 times) "snd_hda_codec: Unknown symbol kstrtoull  (err 0)

Is this just my system, or are we eagerly awaiting further information, or kernel26 2.6.38.4-2?

Re: snd-hda-intel error

Works here... No idea why kstrtoull would be missing... (or where it is supposed to be.)

Re: snd-hda-intel error

Well, someone had a problem with kstrtoull in Debian (also kernel 2.6.38.4) but marked it solved - without the solution being revealed anywhere.
'Unexplained' errors have happened before, with several different distros (including Arch).  I have a standard soluition for this: I will change distro for a while;  just have to choose if I will run Slackware or PCLinuxOs the next few weeks / months / whatever until I can use Arch again.

Re: snd-hda-intel error

wrong solution. this is open source, you can help making things better for you and many users. clone greg kh stable tree and bisect the guilty commit, report it to lkml or kernel bugzilla, it will be fixed.

Re: snd-hda-intel error

Looks like this commit introduces kstrtoull().

Based on my uneducated understanding of the source code, it looks like snd_hda_codec was build with the 2.6.38.4 linux headers, but the kernel is older. Which doesn't make sense, I suppose.

Before making reports, I want to be sure that there is a real error - not just a glitch in just my system. If noone else has the problem, even the most detailed bug report would probably be futile.
Also, I must confess to lazyness - I started programming in1960, but lately I have noticed that keeping up with the ins and outs of more complicated systems is just too much effort for me.

if downgrading to .38.3 solves the issue then there's no doubt about the problem coming from patches from .38.4. Also, it is very possible that only a few machines would be affected by this so don't hesitate to report a bug even if you're the only one. Some users may not use .38.4 yet and will be hit by this bug later when they'll upgrade their distros.

I understand but think of all what you receive from F/OSS, that is one of the best way to give back and make the whole thing better smile

Re: snd-hda-intel error

I have exactly the same error :

[  289.204487] sunrpc: Unknown symbol kstrtoull (err 0)
[  289.207808] cifs: Unknown symbol kstrtoull (err 0)

and before :

How can I downgrade the kernel ?

Re: snd-hda-intel error

Ok downgrading the Kernel from 2.6.38-4 to 2.6.38-2 fixes the issues (I used "downgrade" from Aur).

Network filesystems are mounting correctly now and my missing soundcard is back.

There is definitely an issue with the current Arch kernel version !

Well still no sound due to the move to Pulseaudio from Alsa with Gnome3, but this is another story...

Re: snd-hda-intel error

Ok, upgrading to the new kernel 2.6.38.5-1 solved the problem (as more or less expected).  Now if I could just remember how to change the subject to ... (solved)

Re: snd-hda-intel error

Perhaps ,  as in my case ,you need to select F5 in alsamixer and adjust the speaker volume setting.  I never had to do that until the latest kernels.

Re: snd-hda-intel error

For me the problem still isn't solved :-(

kernel 2.6.38.5-1 is installed
...still: snd_hda_codec: Unknown symbol kstrtoull  (err 0)   (and some other modules as well)

Did you do s.th. special like changing some symlinks or recompile the kernel?
pacman -S kernel26 obviosly doesn't do the trick for me.

Re: snd-hda-intel error

Maybe you could boot into kernel26-lts, uninstall kernel26, check in /lib/modules/ that the 2.6.38 modules are gone (no symlinks or whatever), then reinstall kernel26... That's the only idea I have anyway.

Re: snd-hda-intel error

That actually worked, thanks a lot

I didn't have to remove some symlinks, but uninstall/reinstall of kernel26 fixed the problem
