Public bug reported:
On Ubuntu newer than 7.10, my Thinkpad X31 pauses ca. 2 min at boot, and
than there is no sound at all.
I have tested Kubuntu 8.04, 8.04.2, 8.10 -> with all clean installs and updates
the same problem.
If i install an old Kernel, everything works fine, at least in Kubuntu 8.04.2.
The last working kernel, i can get through the ubuntu repositorys is 2.6.22-15
(generic).
I have collected some Informations about the sound chip on the working
system (kernel 2.6.22-15):
$ cat /proc/asound/cards

The utils_alsa-info.sh script has uploaded its result at
http://www.alsa-project.org/db/?f=61aa8f55ed0cfa5cd7a1a6c7b75d0d3660d64d28
I will attach the output of dmesg with the old kernel and with the new kernel.
I will also attach the output of lspci, it is the same for the old and every
new kernel, I've tested.
