SuSE 7.1 comes with gcc 2.95; it is a bit safer to compile with an
egcs 1.1 compiler because there have been problems with that compiler
version and XFS in the past.

You could compile KDB in if you didn't do it already (it's part of the XFS
tree); then either don't run X or put a serial console onto the box.
When it hangs you have good chances that you see an KDB prompt (it could
be happening already and often looks like a hang in X; if yes your keyboard 
lights should be blinking). Then enter bt and send the results to the list.
It's easier with an serial console to do that of course.

If you get a hard hang it's much harder to debug. In this case it's also
likely that you're running into a generic 2.4 kernel problem; contact
linux-kernel@xxxxxxxxxxxxxxx with your  hardware configuration and setup.
