Thank you for making the time to question my newbie sanity: I do learn
by having people find time to tell me what sounds reasonable or not.
Here now I can confirm,
In linux-2.6.6-bk8 plus my bk8.good.always.patch ...
One way to hang ata-piix.ko is ...
... to expect to copy zero bytes and have the device agree.
For example:
export PLSCSI='/dev/sg0 -X time 5 0'
plscsi -i x12 -x "03 00:00:00 12 00"
plscsi -x "00 00:00:00 00 00"
I then see "Disabling IRQ #18" happen even without my
bk8.good.always.patch, by way of open /dev/scd0.
With /dev/sg0, the command completes, and `modprobe -r` works, but if I
try modprobe again without reboot, then that hangs after again
broadcasting the complaint: Disabling IRQ #18.
As already you saw in fragments, if I clear out the unit attentions with
unsolicited request sense or with my bk8.good.always.patch, then I can
even die despite having seen no error:
kernel: ata_host_intr: BUS_NODATA (drv_stat 0x50)
kernel: irq 18: nobody cared!
