I too have experienced a possibly Athlon related problem. We are running a dual 1.2Ghz Athlon processor system with Promise RAID controller. The system runs for weeks without a problem, reboots are fine, unless you actually shut down the system (power off, not just a warm boot). If you shut it off and let it sit for more than a minute or so it won't start back up. It then has to sit for 15-20 minutes before you can start it again. It has me completely baffled, the system goes all the way throw POST up to where it checks the RAID controller. That test comes back that it is working fine (and it is, I tested it by physically disconnecting a drive and it did report an error) but then the post hangs. Just thought I would throw this one out there, maybe someone has some ideas, maybe not. Thanks for all the great info and assistance everyone here has given me. Before long I hope to start returning the good deeds. Greg Hicks -----Original Message----- From: Tim Prince [mailto:tprince@computer.org] Sent: Sunday, April 21, 2002 8:42 PM To: Robert C.

I just replaced my motherboard/processor. Had a 300mhz Pentium II and swapped it with an AMD Athlon 2000+. I am having trouble in that the system crashes after an hour or so of use. Runs all night if left alone.

I added an extra fan to the case. BIOS reports CPU at 125 degrees F, case at about 95 degrees F. Is this too hot?

Is it possible I should be using a different kernel for Athlon? My flakiest Athlon has SCSI system failures at unpredictable intervals. Something other than temperature seems likely if it can run all night. I'm talking about an 1800+ replacement for a fairly solid 1200. I assume you've checked out the instructions for AGP installation on Athlon, if applicable. -- Tim Prince

If temp isn't the problem, you might try using:

append = "nopentium"

correct me if i'm wrong, but shouldn't this be append = "mem=nopentium" ??

kernel arg in the applicable /etc/lilo.conf stanza.

just a thought.

You may be sitting right on the point of temperature failure. Many commercial grade boards are rated up to 40C (104F). I just did an experiment, not running SETI@Home and Folding@Home for 24 hours so my CPU was idle for most of the time. It dropped the average temperature 5C (9F).

125F for the CPU and 95F for the case is a bit too hot. usually, i get 45C (113F) for my Athlon CPU and 30C (86F) for my mobo on idle. i don't use any special kernel. my advice is to either get a better CPU fan (if you used the one AMD gave you, definitely get a better one). or if your case has another slot for a fan, add one of those. xiaolei
