[olug] kernel panics

[Vincent]

That isn't much info to go on, but here are a couple standard things to try if you still have trouble after replacing the disk:

First, make sure it reboots after a panic.  Add this to /etc/sysctl.conf:
kernel.panic = 3    # System will reboot 3 seconds after a kernel panic
To enable this now:
echo "3" > /proc/sys/kernel/panic

Next, try booting with each of these lilo (or grub) boot options and see if either helps:

Disable machine checking.  This tells the kernel not to check the cpu's data structures.  The BIOS is probably already doing this
anyway and two simultaneous checks can cause problems.
append="root=LABEL=/ nomce"

Disable apic.  This disables the use of IRQs above 15 (SMP or not).  Some hardware has trouble with APIC (Advanced Programmable
Interrupt Control/ler)
append="root=LABEL=/ noapic"
