Hello,
I have the following hardware configuration.
Tyan 2466N motherboard, 1.03 BIOS, 2 Athlon-MP 1800+ CPUs, 512MB registered
ECC DRAM, Onboard 3Com NIC (xl type)
Radeon 8500 AGP video card
Adaptec 3210S SCSI RAID controller
Comtrol RocketPort 8 port PCI serial card
I have started to experience some odd system lockups in the past couple
months, and it seems to be getting worse. I particular, this seems to happen
when the SCSI controller is very busy. I have a file system where I store
dumps of the other file systems. On a weekly basis, I run these dumps. What
has started happening is the system will lock up completely during one of the
dumps. When this happens, the system is totally unresponsive. Even at the
console, it is dead to the world. However, the status lights on the RAID
controller seem to indicate that it is happy. The system has to be power
cycled at that point. I have been unable to generate any debug information to
help chase this issue.
I have also had some issues with mozilla locking up and it could not
be killed. When I exited from X, the system would lock as described earlier.
As a desperate measure to try and get a backup, I built and installed a
single CPU kernel. That seems to be resolving the problem. However, it would
be nice to bring the 2nd CPU back on line. I looked through all the BIOS
options, and I don't see anything specifying the MPS version. I would be
happy to assist in troubleshooting, but I really don't know which direction
to go at the moment. I have attached both kernel configuration files and
dmesg output from both during the boot process.
Any suggestions???
Thanx,
EBD
