Volume Control buttons not working after kernel upgrade [SOLVED]


My laptop is setup as a dual-boot with Arch and Debian, and I've been running various custom 2.6.9 kernels on it, with no problems. The following applies to both distros.

I've now compiled 2.6.10 kernels, using the existing 2.6.9 configs and "make oldconfig". Compilation was uneventful, and the laptop boots into 2.6.10 with no errors.

I'm running alsa, and under 2.6.9, I could adjust the volume either with software (alsamixer, xfce4 volume control) or with hardware (Fn+PgUp/Fn+PgDn, or dedicated Volume Control buttons). Under 2.6.10, software volume control is fine, but if I try either of the hardware options, the machine locks up hard, and needs a reboot. After reboot, I can't see anything useful in the logs.

If anyone has any suggestions, I'd appreciate it.

Well, this is the problem with not forking to a 2.7 'development' kernel and leaving the stable one alone, things get added that break other things. If the changes you made are only to the kernel, and affect two separate distros then it is most likely a kernel bug. You can file a bug report if you like.

If you cannot live without the hardware volume control I suggest downgrading your kernels again and wait till this issue is fixed.

Thanks for the advice, bulliver.

As it happened, 2.6.11 was released yesterday, and it solved the problem.

Of course, I still don't know what the problem was....
