System: NetBSD whitewater.jtec.com.au 1.2D NetBSD 1.2D (WHITEWATER) #11: Sat Mar 22 14:40:11 EST 1997 stephen@whitewater.jtec.com.au:/usr/src/sys/arch/i386/compile/WHITEWATER i386

>Description:
During bootup, the device probe/attach routines run with no problems. The
kernel reaches the swapconf() call in autoconf.c and hangs. (This HD
activity LED stays lit after the kernel hangs). A DDB backtrace
indicates the kernel tsleep()ing in scsi_exectute_xs(). This is, I presume
the first drive system call after the device probe/attach has completed.

As far as I can see, aha_scsi_cmd() is called correctly from that
scsi_execute_xs(), but aha_intr() is not subsequently called.

I can see aha_intr() being called during the probe of the scsi bus.
There appears to be a spurious aha_intr() going off at the
spl0() call in configure(). This last call is probably confusing
aha.c

>How-To-Repeat:
Try booting a recent kernel on a machine with an Adaptec 1542B.
