Alex:

I apologize for not being more specific in my questions. I understand 
that we're loading the firmware via the kernel, but my question was why 
not load it from the card? If I have an HP SmartArray 5300 card and the 
firmware is out of date, I'm expected to update it, not load a kernel 
module to do it for me. This makes sense for many reasons, not he least 
of which is compatibility. I'm in no position to suggest what is proper 
from the standpoint of this particular problem, but I'm trying to 
understand the reason for choosing a kernel module rather than an sys 
admin as with nearly all other devices.

I misunderstood the purpose of your patch as well. I thought the problem 
  was a firmware loading issue, but as you mentioned, this does not 
appear to be the case.

I did see your message with the patch and it was correctly applied and 
the kernel was correctly compiled. I did, however, reinstall the OS 
because of all the fiddling I did to this point. Funny thing is that I 
can't get it to crash anymore. I tried it clean, and the system tanked, 
but after I applied your patch, I can't get it to panic anymore. The 
loop looks like it comes up, but when I rescan with the initiator, the 
target stays up without incident, but nothing shows up in camcontrol as 
an emulated disk:

amd_svr0-01# camcontrol devlist -v
scbus0 on isp0 bus 0:
<  >                               at scbus0 target -1 lun -1 ()
scbus-1 on xpt0 bus 0:
<  >                               at scbus-1 target -1 lun -1 (xpt0)

I do get this on the initiator though:

After a clean install, this is what I see from dmesg on the target:

Not sure what to make of this.... Would you recommend a different FC 
card? Emulex?
