SubjectKernel crashes
Hi there, 

In the last 3 weeks I get really hard crashes of my Linux system. I'm nearly

sure that this isn't a hardware problem because (don't hit me :) watching TV

under Win for hours or playing games has never resulted in a crash.
The most time it crashes is when I'm compiling something and another
filesystem (like cdrom or vfat) is mounted - I don't know if there is a
connection. The crashes are so "hard" that fsck stops to run automatically
and I have to do the work manually (deleting / fixing).
If the kernel crashes I have never got a message in var/log/messages.
Yesterday was the first time that I was able to see a message.
I don't know what to do - I can't figure out where the problem is.
With test6 I encountered the following: if I shutdown the system it hangs on

my SuSE 6.2 at the line "Shutting down lpr".
I really really really don't know what the problem is because the only 2
error messages I get are shown at the bottom.
So, I'm not a programmer and I'm not involved in any kernel-related things.
But I need my Linux machine for working, so I don't want to test _any_ new
version that is not beta. And if my machine always crashes the "hard" way
I'm loosing data / files - and that's hard for me.
Please tell me (via e-mail) what I can do.

Thank you,
Dennis
