Hi,
During kernel compilation (or other heavy use of the machine), the
machine
locks up. No oops, no alt-sysreq, only a hardware reset is
possible.
Machine is a Toshiba CDT 1640 laptop: 475 MHz K6-II+, 128KB cache, 64 MB
ram, Aladdin V chipset, 6 GB Fujitsu hd.
Observations:
The standard RedHat kernel (2.2.16) and Windows work fine, so it doesn't
seem to be a hardware problem.
When the machine locks up, the little fan begins running immediately,
which means the processor is getting very hot (doing what ?)
I've tried various settings of the IDE driver (disabling dma etc.)
thinking it might be an ide problem, but this didn't make a difference.
"make bzImage" reliably locks up the machine after a few minutes, but
not
at same the point in the compilation.
I don't know if the problem is related, but the audio driver for the
cs4281
sometimes "stutters" during playback.
Let me know if I need to supply more information, apply patches etc.
Many thanks,
Pieter van Prooijen.

Except likely it is hardware.. the plastic case :)

Compiling is very cpu intensive, so the system won't be doing many
idle calls (where cpu can cool down). This sounds like your cpu is
having a heatstroke and shutting down instead of frying itself.
It may well be that 2.4 kernel is keeping the cpu busy more than 2.2
or windows does, and your box is poorly designed wrt heat disipation.
