Subject: AIC7850 panic (post 2.4.14)

I had the exact same problem with this chipset (Adaptec 2904), but I
increased the "Initial bus reset delay" from 150 ms to 250 and solved it.
By the way, do you have cdrom's attached to your scsi card? Beware,
since 2.5.1-pre8 (at least) the PC will hang solid if I try to mount a
data cd. Up to 2.5.1-pre11 the problem remains. Can you verify this
(without mounting any disk, of course)?

I've tried that, and also reducing TCQs to 8 as suggested elsewhere.
Unfortunately it hasn't solved the problem, it just takes longer to die.

Yes, the card drives a CDROM unit and a DVD-RAM drive.
However I don't intend to try 2.5 for a good few months yet.
