Most probably it is the lapic which is known to cause problems like that
on thinkpads. Had the same problems, too. If you make a new kernel, just
do not enable the lapic (under "processor type and features" it's "local
apic support on uniprocessors"). Maybe there is also a kernel parameter
that will do, but I don't know for sure. Maybe someone on this list can
help out.

Anyway, what about getting a new kernel, like 2.6.10 which runs really
stable for me.
