Hello,
I manage to crash the kernel 2.4.20 of my gento three times.
I have probably an error in my gentoo installation but the kernel
couldn't crash as it do.
This is theway to crash my wrk:
in a gnome-terminal, I do emerge dia.
in the configure script he write an error, (it cannot verify a header
file).
The load to 3.5 and more so I do Ctrl-C. It write it recieve the signal
but don't stop. I try to kill the ./configure script or the python
emerge script with kill -KILL pid but that didn't work. I switch my wrk
to console with C-M-F1, and CRASH ;-) The local display freeze If i try
to log on, the kernel continue to route normaly the packet and I can log
on with ssh but ...
