I got a few oopses today with 2.4.6. Someone reported this with
2.4.5 too some time ago, but didn't see anything about it yet.
It always kills the currently running program with a SIGSEGV.
First I got two at the same time, this happened when I was
compiling the kernel. After some time everything started having
the problem. The third is from when I tried to run the oops thru
ksymoops.
Output of ksymoops is attached.
