XP1000 667 mhz locking up.

[Todd Henderson <Todd_Henderson readwo com>]

I have 34 identically configured XP1000's and recently one of them began
to lock up spewing this information to the console:

 +0 8000000000000080 5800000018
 +10 100000086 0
 +20 8 2baaa40

TSUNAMI_pci_clr_err: PERROR after read 0x0
TSUNAMI_pci_clr_err: PERROR after read 0x0


This all started after we had a UPS/power failure for the whole computer
room.  I've rebuilt the system drive.  Is there an indication here as to
where to look?  The kernel version is 2.2.5-16.

Thanks,
Todd
