Not likely... usually kernel problems are not due to kernel options, but
due to bugs introduced in the new kernel. The way to solve kernel problems
is to either go forward or backwards in the kernel version.

Impossible - apps don't freeze the system

Not possible - works fine in Windoze, and problems are reflected in other
people's laptops

Not likely, unless it were to turn the CPU frequency down to 0 for
whatever reason.

Might help determine if it's a stress-related issue, but it won't have
anything to do with any given application.

... or anything else with a different kernel version. Better yet, find a
kernel version that is reported as working with your laptop model, and
possibly a fine-tuned kernel for your laptop. These are common.

... which would then suffer the same problems that he's suffering due to a
kernel bug.


On another note, I've found that NFS doesn't work properly under 2.6.25-r7
on some machines... it will cause the filesystem to lock up wherever NFS
is involved at random points. Forces you to hit your power or reset button
to recover (normal shutdown not possible due to lack of timeouts and
recovery mechanisms). The machine I've noted this on was an nForce 750i
chipset.

The NFS server was a FreeBSD 7.2 machine, the client being described
above. TCP packets were used instead of UDP to eliminate the possibility
of dropped packets.
