Hi,

I have a strage problem with the kernel version 2.6.3. Whensoever
chkrootkit is run, the following kernel oops is thrown:

Systems (a bit outdated, ok...)
Pentium MMX 200, Intel 430TX, IDE, vanilla 2.6.3
Pentium MMX 233, Via Apollo VP2, IDE, vanilla 2.6.3
Pentium II 450, Intel 440BX, SCSI, vanilla 2.6.3

All with noACPI, PREEMPT, APIC and Debian Sid.

It seems that's something to do with preemtion... that's
all I can guess. Kernels <= 2.6.2 are doing very well
(with PREEMPT enabled)

Any hints?


ciao, phb
