[ale] Stack dump

[PairOfTwins]

Anyone:

Replaced the motherboard in a working Ubuntu 7.04 installation, after 
lightning struck, with a NEARLY identical motherboard (same brand and 
same ViA chipset), expecting to have a working system.

Nearly every boot, I get a stack trace, etc, but can't pin down the 
problem, unless it's SATA hard drive stuff.  Running e2fsck didn't turn 
up any errors.  Booting Xubuntu from CD works fine.

"BUG: unable to handle kernel paging request at virtual address 00002361
Printing EIP"

Once, with several SATA features disabled in BIOS, it booted, but next 
boot the old errors came back.

My googling turned up some kernel parameters to try -- none of which 
helped:
   all-generic-ide, pci=nomsi, acpi=off

Any suggestions, short of reinstalling?

Thanks,
Tom
