Qlogic FC scsi_target ISP2310

[Fuujin Networks LLC]

I've run into a snag with our SAN and I'm hoping someone out there can 
shed some light on the glass, as it were. We're trying to use 
scsi_target mode with a pair of QLogic ISP2310 2GB fibre-channel cards 
in a Point-to-Point topology. These cards will NOT be part of a switch 
fabric. I started out with a quad port card, and when I rescanned the 
SCSI bus on the initiating end of the loop, the target machine tanked.
The filer dumps core, reboots, and reproduces the result faithfully.

Thinking I might be doing something wrong with port selection, I pulled 
the quad port card out of the SAN filer and installed a single port 
card. After several days of jiggery pokery with all manner of knobs, 
AIO, etc, I've ended up with the same result: a 64-bit space heater. :)

I've Googled this to death, crawled the lists, and I've not found a 
solution other than the occasional "it might be buggy" comment. Full 
kernel traces are available to anyone interested, possibly even ssh 
access to a test box if requested. I've been running FreeBSD for about 7 
years and I've never seen an operating system as stable, so I'm rather 
determined to make this work than go to Linux.

The filer is running FreeBSD 7.0 amd64, dual Opteron 2216's, with 8 gigs 
of ram. I've tested this on a pair of HP DL580 G3's to see if there was 
a difference from 32-bit to 64-bit hardware, but none was apparent.

Any help is greatly appreciated!
