2.6.5-rc2 - panic when slocate.cron job accesses firewire disk

[Robert Gadsdon]

I get the following when the slocate.cron job accesses the first of 3 
120GB firewire disks:

(copied/OCRed from screen photo)

When booting and mounting the disks, the console shows the following 
'errors/warnings':
ohci1394: fw-host0: Unexpected PCI resource length of 1000!
........
ieee1394: unsolicited response packet received - no tlabel match

Similar problem occurs with 2.6.4, but 2.6.3 and earlier are OK.

System is a 2-cpu PIII (Via) running Fedora 1 with 2.6.x kernel..
