Hello List,

I reported frequently system lockups today.
Now after some playing around (cause I don't know anything about kernel
debugging - Thanks to Mark Hahn for the tipps)
I found a way to reproduce the lock and to get the OOPS.
Dan Kegel told me after the last post that only kernels built from the
kernel.org sources can be supported
by this list. I now used the 2.4.20-2.25smp kernel from RawHide. And I
didn't build a kernel from kernel.org.
O.K. here's the deal:
The OOPS below looks like spanish to me but for the hackers the thing could
be very clear.
So if you think that is a common kernel issue please help. Otherwise I'll
report to RedHat immediately.

Scenario:
2.4.20-2.25smp from RawHide

Doing a rsync from the crashing host _to_ another host over a 1000 Mbit 3com
(TG3).
The rsynced files include bigger files with about 1.5 gigs.
Heartbeat runs.

Below are the OOPS.
Please CC to dk@webcluster.at if you are wanting to help.

Thanks a lot

Daniel Khan
