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):

FATAL: Error running install command for slamr
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.
