isp panic with 64-bit card

[Staffan Thomén <duck%shangtai.net@localhost>]

Hi, I have an AlphaPC164 that has two scsi boards, an isp1020 and an isp1080, my
system boots off a disk on the 1020 and the 1080 is hooked up to an external
disk array of some 12 disks.

The 1080 is a 64-bit card, and works fine in a 32-bit pci slot. If I plug it
into a 64-bit slot it works for a little while (I can boot up, read from and
write to disks) and after a few minutes the kernel panics with:

isp1: Not RESPONSE in RESPONSE Queue (type 0x2) @ idx 25 (next 26) nlooked 1
isp1: Request Queue Entry:

isp1: 0x00000020: cc 01 43 00 00 fc ff ff 30 9a 25 00 00 fc ff ff
isp1: 0x00000030: b8 38 cc 00 00 fc ff ff 06 00 00 00 00 00 00 00
panic: kernel diagnostic assertion "(l->l_pflag & LP_INTR) == 0" failed: file "/data/tmp/src/sys/kern/kern_synch.c", line 187 
spopped in pid 0.5 (system) at  netbsd:cpu_Debugger+0x14:       or      zero,s6

Is this just that the card isn't designed to operate on a slow bus in 64-bit
mode or a kernel mistake?

I'd love the increased bandwidth, but this is obviously not a high profile
target... :-)
