Thank you very much for everybody that helped with the problem
that I have. I'll be checking the hardware of the machine and
I'll let you know what the results that I have are (i.e., if
the problem is indeed with cooling or with other hardware
part).

Meanwhile, I'm having other problems when I use a kernel
2.2.19 in a computer with an Adaptec card.

I get a lot of messages saying "Data overrun detected" when
there is any slight disk activity (like the init scripts being
loaded during boot). When the disk is almost idle, I don't see
these messages, but if I trigger something (like a find
process) that does something a bit more intense, then I get a
huge number of these messages. I'm sending a dmesg attached to
this e-mail.

I don't see any such messages with kernel 2.2.18. Are these
messages "dangerous" in any way? May it be the case that these
events are also occuring when 2.2.18 is running but it is not
reporting, while 2.2.19 is? Is there any potential bug with
the hardware?

The machine in question is a Samba server with low load
generally.

BTW, reading Alan Cox release notes
(http://www.linux.org.uk/VERSION/relnotes.2219.html), I see
that between kernels 2.2.18 and 2.2.19, the AIC7xxx driver was
updated. May that be a cause of the problem?

Is there any other information that is necessary? I see no
Oops this time, BTW.

Thank you very much for any help, Roger...
