kernel BUG at page_alloc.c:75! / exit.c

hi,

I'm running the 2.4.3 kernel and my system always (!) crashes when I try
to generate the "Linux kernel poster" from lgp.linuxcare.com.au. After
working for one hour, the kernel printed this message:

I think there should be more, but it stopped at this point.

Do you need more information about the system?

Thank you, Felix

none of the above, but the CPU (Athlon) temperature is at ~65 °C. Is
this ok?

thanks,
Felix

This is *not* a hardware problem.  We're tracking something fishy in the
vm code that is resulting in exactly the same BUG() tripping up on a
number of boxes (4 and 8 way SMP).

Hmmm, my (BIOS)default is to shut down at 56 C.  Normally runs between
40 and 42 C.  This is with a 750 Mhz Athlon.  Nothing in the docs says
what is acceptable.  Maybe check out the AMD web page.
