"Firmware timed out" with qlogic 2312 FC cards

[Leo Prasath Arulraj]

I did that and made sure kldstat displays isp_2300 after boot.
But the error still persists.

I also see spurious interrrupts from the device. But not sure if they 
signal something wrong:
  "kernel: isp0: bogus intr- isr 8013 (8013) iptr 276 optr 276"

Aside, I am trying to use a code "Memulator" ( 
http://www.ece.cmu.edu/~griffin2/ ) which was developed on FreeBSD 5.2 
with Adaptec 21960 scsi card. This tool emulates a scsi disk ( much like 
/usr/share/examples/scsi_target ).

Can someone recommend a SCSI card that is on market today which is most 
likely to work on the FreeBSD 9.0 in target mode ? This will be very 
helpful.

Thanks,
Leo.
