The drive in question is Seagate 8 GB internal ATAPI drive. I have had it on an Intel VX430 chipset motherboard, kernel 2.2.x and now I have on an SiS 5571 chipset motherboard, running 2.4.7. The problem occurs whey I attempted (by mistake) to write QTR-1 tape in a Travan 4 drive. The kernel panics. When attempting to read the QTR-1 tape, an error about getting too much data starts occurring and then there is 'lost interrupt' message as well. This doesn't cause kernel panic. Writing/reading 8 GB cartridges is perfectly fine. It is very easy to replicate the problem (happens every time) by doing the above. I used tar to write to the tape. This is not necessarily very important, but it might save someone a few headaches when they insert QTR-1 tape into a Travan 4 drive by mistake or on purpose. Especially if the machine is otherwise important and is not supposed to be rebooted :-) Bojan PS. Bojan's Law: "All tape cartridges look the same at 6:30 am".
