Well you've been having fun there. I'd say that you've hit two (maybe 1.5) bugs in the scsi code: - I assume that your high-priority task has starved a scsi kernel thread for so long that when that thread finally got control, it decided that something had timed out and declared an error. Maybe. Or perhaps the card decided that it hadn't been serviced for so long that it declared an error. It would need someone who is familiar with scsi and aic7xxx to determine that. - In response to the timeout, aic7xxx error handling went and passed crap into the scatter/gather unmapping code and the kernel oopsed. Frankly, I doubt if either of these things (or at least, the first one) are likely to be fixed in a hurry and I'd suggest that you look at continuing your work on (say) a SATA or IDE machine, sorry. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
