Missunderstanding. I ment, since it is not much more than 50 degrees
I do not expect it to become unstable, but maybe I'm wrong and 50
degrees is already to much for a Pismo or the TAU is very much off.

I added a second RAM module about 2 years ago and have been running
2.6 for about 3 month. The current problems are about as old as the
switch to 2.6. Replacing the RAM required to remove the head
pipe and to put it back on. Could it be that this has bad influence
on heat dissipation?

Anyway, if heat is the problem, is there any cure?
