Hi,
Today, my freshly updated Netra T1 which serves NFS to all my
sparcs... (including pkgsrc and package binaries) started to be not
responsive.
I attach serial console and find myself in the debugger, stacktrace
looks like in an drive, I type continue and see a stream of this:

of course, haard disks can go havoc... the Netra has two hard disks,
sd1 is the one which serves files.
Or could it be that NetBSD 10 isn't that stable? Network and Disk I/O
caused trouble?
I quickly power-cycled. System rebooted, fsck'd volumes mounted and
NFS worked, no more SCSI errors. NFS resumed and worked until I shout
down everything for Friday evening.
Will retry next week... but looks like esiop0 did hang up on sd1!
