Hi,
I have a Dell Inspiron 5150 laptop that has been running FC1 for the last year (or so). I took the plunge last weekend and did a clean install on the machine with FC3. Very impressed by the smooth installation, and initially very happy - especially with "yum update" very neat!
However, the machine is now "freezing" on a semi random basis, particularly under heavy load. Though, I left it alone idling today and when I came back it had again frozen. When it freezes under load, the CPU fan can be heard at (I guess) 100% for a couple of minutes while it is frozen, then shortly after the machine powers itself off. The last couple of under load freeze were at the same time as the CPU fan stepping up another "gear".
The freeze happens when running under 2.6.10-1.760_FC3smp (the machine is HT with a 3Ghz Intel processor) and also 2.6.10-1.760_FC3.
With acpi=off, the machine appears to be stable.
With FC1 I was able to run this laptop with acpi=on (only with uniprocessor mode, didn't trust HT with 2.4), without any problems with stability.
Unfortunately, nothing of interest is being written to /var/log. Is there a recommended mechanism of debugging this fault? Any pointers to other things that I can configure (e.g., could the CPU speed stepping be the source of the problem?)
Thanks, Peter.
