Please describe your hardware completely:
motherboard make and model, bios and firmware (BMC etc) revisions
cat /proc/cpuinfo output
Also please tell us exactly what kernel you use (not just the version, but
rather the procedence plus all patches you applied, and which compiler you

That will make the machine very, very suceptible to less-than-perfect PCI
bus implementations, and to kernel bugs. I have one acting as our core
router here, which teached me to not trust 3COM 3C905B boards anymore, for
OTOH, you are using probably the best network card available for Linux ATM

1. PCI problems (hardware fault)
2. SCSI/PCI routing kernel problems (software fault)
3. CPU/memory instability (hardware fault)

If you are using a vanilla kernel, stop doing that now. Get the latest
Debian patched kernel (2.4.27-8) from SID and use that, or get the RedHat
kernel from SID (it is available on Debian) and use that.
