isp(4) annoying problems on PWS500au

[Nicolas Joly <njoly%pasteur.fr@localhost>]

Hi,

I'm seeing some isp(4) problems on a PWS500au running up-to-date
-current NetBSD/alpha.

1) I get numerous console messages while copying some datas on
disks. By example, when installing a newly compiled 10M kernel to /

isp0: unable to load DMA (35)
sd1(isp0:0:1:0): adapter resource shortage

2) I cannot reboot without resetting the machine at the srm
prompt. The isp(4) scsi controller seems to be stuck ... (just to be
sure, i swapped the PWS500au motherboard with a spare one and got the
very same hangs).

Any idea ?
