Hi

Since I upgraded my Digital Personal Workstation from NetBSD 4 to 5, the 
machine is having an annoying problem with the QLogic isp(4) SCSI:

After halt(8)'ing the system, the SRM console goes "waiting for pkc0.7.0.1004.0 
to start..." for a minute and all the scsi devices have disappeared. I have to 
do an SRM "init" to get back to the correct state and to be able to boot an OS.

Notice how even the "5.57" after "SCSI Bus ID 7" has gone away, see below. This 
is what it should look like:

btw. SRM version is 7.2-1

Could the major update to the isp(4) driver (dev/ic/isp.c rev. 1.111 among 
other files) have something to do with it?
"Testing has been principally on amd64, i386 and sparc64 and seems to
not have broken things for me."


Here's the boot dmesg:

Any help is appreciated!

>How-To-Repeat:
Halt or Reboot the running OS. The scsi devices will no longer show up in the 
SRM device list (until the SRM is reset).
