No LUNs detected with 2.6.1-mm4 qla2xxx / qla2300

["Michael W. Shaffer" <mwshaffer@yahoo.com>]

I have the following (briefly):

- HP NetServer LH6000r
- 2 x QLogic QLA2340 2GBps HBA
- 2 x Nexsan ATABoy2 RAID Array

The server has two HBAs in it. One HBA connects to
one array, the other HBA to the other array (duh).

Running kernel 2.4.21-xfs with the Feral Software
ISP driver loaded as a module, everything works
fine (well, except for the fact that 2.4 is a total
POS under I/O load...). Two HBAs detected, one LUN
shows up on each HBA, two SCSI block devices sdb
and sdc are registered, RAID1 across them, XFS file
system on /dev/md0 -- everything is happy.

I just compiled kernel 2.6.1-mm4, which includes
this merged version of the QLogic drivers called
qla2xxx. I built the qla2300 driver as a module,
and when I load it, the HBAs are detected just
fine, and I see their port and node IDs, but no
LUNs are detected, and no SCSI devices registered.

Apparently this new driver is my only option now.
I tried the qlogicfc and cpqfc drivers, but they
don't appear to recognize the HBAs I have at all.
The factory QLogic drivers don't work with 2.6,
and the Feral ISP driver was dropped from the -mm
patchset back around 2.6.1-test5 or so, apparently
because it is considered 'old and broken' (at least
with respect to 2.6, I've had very good results
with it so far in 2.4).

I can see on the status monitor for these arrays
that their ports change from 'Loop Down' to 'Loop Up'
status when I load the qla2300 driver, so it looks
like the HBA is being initialized and is joining the
loop ok or whatever -- it just doesn't give me any
disk devices to use. Reboot the system with the old
kernel -- everything works fine again.

Output of dmesg and contents of /proc/scsi/qla2xxx/*
below, any advice would be greatly appreciated.
