[Pkg-alsa-devel] Bug#431775: Kernel BUG doing `alsactl store` on ThinkPad T61 [HDA Intel/AD1984]

Wed Jul 4 19:23:01 UTC 2007

Package: alsa-source
Version: 1.0.14-1
Severity: important

Hello,

After installing alsa-source and building the module package, I now get
a kernel BUG when doing `alsactl store`.  Furthermore, since this is
executed upon shutdown/reboot I can no longer shut down my machine
cleanly.  Here is the BUG output:

BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:
