Re: PROBLEM: <BUG Report: kernel BUG at slab.c:1062! from pppd with speedtouch drivers and pppoatm>

[Richard Purdie]

It was mismatched module versions that casued the original bug error. I had
recompiled the speedtouch module itself but not the sarlib library it uses.
My fault, sorry :(.

Now I'm back to the kerenel panic below which takes down the system at the
same point as before:
It also did this on 2.4.5. It sometimes does and sometime doesn't happen but
always at the same point.
I'm going to try with 2.4.2 and see what happens from there.

Kernel panic: Aiee, killing interrupt handler!

It doesn't look very helpful to me. I'm sure the numbers are right but they
were hand copied.
