I don't know if this will help at all, but I've run into similar problems on some systems that have AIC7870 controllers embedded on the motherboard with *no* SEEPROM. It appears as though SCSI bus disconnect is not being set - writes to the disk while the tape drive is busy guarantees a panic. I've experienced this with both 2.1.0 and 2.1.5 - not tried it with 2.1.7.1 yet. The only workaround I was able to do was to install an AHA2742 and stick all my devices on that. If you want me to recreate the crash and provide info on it, lemme know. Can do. Not a problem. :) Regards, Sean. +--------------------+----------------------+------------------------------+ | CCS: Western Cape | Tel: +27-21-462-2780 | DISCLAIMER: Any opinions ex- | | Private Bag X1 | Fax: +27-21-462-2791 | pressed above are *MINE*!
