I'll keep track of it. I have some updates. After turning the portable
off last night, I turned it on this morning, and the problem seemed to
have disappeared... the process was not eating cpu anymore. I started
X, and the fan started working briefly, then stopped when I left X. I
did a reboot, and things were still OK. Then, when I started a 'make
menuconfig,' the fan started working again, and exactly then the
process began again to eat 99.9% of the CPU timæ.

The problem is really connected with fan operation: if I go look at
/proc/acpi/fan/FN00/status, I find

status:       off

while the fan is instead very much in operation. If I do

echo 'on' > state

the content changes to 

status:       on

but if I then try to write 'off', mothing changes. Can this all be
useful for tracking down the problem?

I read something (and I am under deadline for my work... grgrgr) about
all this, but I could not learn enough to be confident with the
process. 

Maybe later...

Thanks in all cases
