It says "spurious interrupt" and kernel panics. If I turn the BIOS OFF on the empty card, all is well. If I connect the external case to the previously empty SCSI card and boot (with BIOS enabled) and I try to read from the tape drives using DD, I get 'data overrun' errors. If I disable the BIOS the errors go away. This happens with stock kernels 2.0.32, 2.0.33, 2.1.87, 2.1.89, and 2.0.33 w/ 5.0.7 AIC drivers. Any ideas? Derek L.
