Package: sl-modem-source
Version: 2.9.9d+e-pre2-2
Severity: normal


On a Debian 2.6.15 kernel and the ALi5451 chipset, I get an oops when 
inserting the slamr module.

Let me say at once this may be due to a problem in ALSA, as I get this 
on boot, so maybe the bug report should just go there (I'll report 
separately to lkml):

AC'97 1 does not respond - RESET
AC'97 1 access is not valid [0xffffffff], removing mixer.
ali mixer 1 creating error.

On the other hand, the mixer and other parts of alsa actually work fine.

On boot (if not blacklisted in udev):

On this oops, the OS doesn't crash, but it becomes largely useless as 
other modules won't insert and the slamr module won't remove.

This same sl-modem-source package works fine on kernel 2.6.12 on the 
same machine.
