I have a sparc 5 running sunos4.1.3 which I'm trying to use rdump/rrestore
to a HP35480 tape drive on my amiga3000 over ethernet. The dump part seems to
work fine, but I can't use remote restores from the sparc, because it always
causes a kernal panic on the amiga. I'm basically just doing a
'restore ivf amiga:/dev/nrst0' from the sparc, and the amiga just goes down.
The amiga's console message is:
panic: vmapbuf: null page frame
Which then drops me into the kernel debugger. A trace shows basically:
( There's lots of numbers and such that I've omitted from the trace, but I can
supply them if they'd really be useful).
The tape drive appears to work fine for local dumps and restores on the
amiga, with the exception that 'mt -f /dev/nrst0 status' always reports:
unknown tape drive type (7)
This is with a reasonably current kernel, compiled from last week's
tarballs. It also happened on on my older kernel compiled from
I thought I'd just mention this as a bug report. If there's something I'm
doing wrong, I'd appreciate it if someone pointed it out.
