Unfortunately, yes, I am still able to trigger an oops doing a bru backup
of my system. It does not oops while doing a tar, so it is most odd. I
don't think it's hardware related, because I have seen no other symptoms
of bad ram or flaky equipment. So far I am only able to trigger this
using bru from BRU2000-15.0P-2.
I am in the process of relocating, so I will be unavailable for several
days before I can test anything else (hence the reasons for doing the
backups :) Suggestions in the mean time are welcome, however.
At any rate, here is the oops. Additional information will be available
after Thursday if neeeded. Just for reference: 486DX4-133, PCI BusLogic
932 backing up a Quantum 6.4 ST SCSI on channel 1 to an HP C1533A DDS2 DAT
on channel 0 of the BusLogic.
