Re: System crash

[Robert Nestor <rnestor%mac.com@localhost>]

I didn’t realize at the time that the iso file I was using for this was on an NFS share.  It crashes there, but if I move the file to a local disk then I don’t see any crash and get the same output you got.  This is the BT for attempting this when the file is on an NFS share:

cpu1: Begin traceback…
vpanic() at netbsd:vpanic+0x152
snprintf() at netbsd:snprinf
nfs_pathconf() at netbsd:nfs_pathconf
VOP_STRATEGY() at netbsd:VOP_STRATEGY+0x64
vndthread() at netbsd:vndthread+0x81e
cpu1: End traceback…
