Hi,

while trying to get some more FC disks attached to an API CS20, I
installed a Qlogic ISP 2100 controller in one of the two 64-bit
PCI slots.

Initially I tried it in the bottom slot, and I could not get the
machine through the autoconfig phase; after probing the
controller as

isp0 at pci0 dev 5 function 0: QLogic FC-AL HBA
isp0: interrupting at dec 6600 irq 24
scsibus1 at isp0: 256 targets, 8 luns per target

it started spewing spurious interrupt errors later while probing
the drives:

tors
stray 6600 irq 24; stopped logging

and at this point it hung while it still has 5 more drives to probe.

Moving the card to the upper PCI slot made it go further, but it
still does not work reliably.  With the card in that position, I
can create the raidframe raid, but it will again start spewing
the spurious interrupt messages at the moment I try to do newfs
of a partition covering most of the raid.

Why does these messages occur?  Isn't the controller / driver
supposed to handle these interrupts?

The built-in fxp1 chip which sits on the same bus works fine.

Hints for further debugging would be most appreciated.

I've also tried to get an LSI Logic FC909 controller to work in
this machine, but it encountered other possibly unrelated
problems -- after a short while the driver prints

mpt0: Unknown async event: 0x2
sd2(mpt0:0:1:0): command timeout
mpt0: timeout on request index =3D 0x3fe, seq =3D 0x0000166d
mpt0: Device not running

and thereafter appears to be completely dead.

Full dmesg for the latest boot with the Qlogic controller
installed follows attached below.  The "stray irq"s go together
with my attempted newfs.

Regards,

- H=E5vard
