I guess the glibc build was ongoing:
drwxr-xr-x  5 buildd buildd 4096 Apr 14 21:32 glibc-2.5/

I guess we have discovered some kind of kernel exploit or at least DoS
as a kernel crash based on whatever the userspace does is unacceptable.

I was just observing the crashes and as i got more than "machine is
dead" i felt like better send it people. My hope was that Thiemo or
someone else knows about this and can tell whether this is fixed in
the current etch kernel.

Selfmade or Debian kernel ?
