[KSYMOOPS] Memeory related errors killed SMP box

[KSYMOOPS] Memeory related errors killed SMP box

Hi,

I downloaded and installed today's CVS ALSA and the
following happened:

- no sound when using aplay
- complete X-server lockup when trying to load OSS
emulation modules. (Machine still pingable, though.)

On reboot, the same thing happened except this time I
received an oops. (Attached.) I strongly suspect
today's memory-related changes.

I am using a SB-Live! card with Linux-2.4.19-SMP.

Cheers,
Chris
