I'm working on a device driver for the UltraStor 24F SCSI adapter.
The drive detection during boot works (using polling instead of
interrupt driven I/O), but later when the kernel reads the disk
label I get "ISA strayintr 7" and the machine hangs. I'm guessing
the command complete interrupt is getting delivered at the wrong
interrupt level (because I get one too many interrupt 7 and one
too few interrupt 10). Any suggestions on how to fix this?
Once out of several boots I got past this point, so if it is a driver
bug it is an intermittent one.
This is an EISA card. Do the interrupt controllers need to be programmed
differently for EISA?
