Okay, I finally got a chance to get a recent 2.3 kernel to boot
(almost) on my Miata past the PCI probing stuff. Unfortunately, all of
my disks hang off of two QLogic ISP1040B adapters (aka KZPBA-CAs for you
DECies/PAQies). So...with 2.3.22, I get some mention about
"qlogicisp : unable to decode i/o address 0x8100" for one, and the same
just with 0x8200 for the other.
If I go back to my 2.2.12 kernel, I see base addresses of 0x9000 and
0x9800 respectively. I went to check the data that the io_base was
pointing to (which was what caused the query to fail) and got back
0xffff for what should have been either the PCI_VENDOR_ID_QLOGIC or the
PCI_DEVICE_ID_QLOGIC_ISP1020. Needless to say, that's not quite the
right answer. So, I changed DEBUG_CONFIG to 1 in drivers/pci/setup.c
and got the following for a boot log. The rest of the boot log
disappeared after the serial init, but the end result is the same. I
can hand copy one if someone would like.Anyone have any idea what
happened here, or a better way to continue debugging this? Thanks!

P.S. Sorry for the long log at the end...
