The new DMASCSI-CRT kernel works great.
However... :)
I can access partition c just fine on my newly labelled
SCSI drive. I can't access any other partition.
I can dd, newfs, etc... on /dev/rsd0c. Accessing any
other partition returns:
# newfs /dev/rsd0a
newfs: /dev/rsd0a: open: Device not configured
# dd if=/dev/rsd0a
dd: /dev/rsd0a: Device not configured
# cat /dev/rsd0a
cat: /dev/rsd0a: Device not configured
Disklabel (both with and without -r) reports:
# disklabel sd0
# /dev/rsd0c:
type: SCSI
disk: hp3725
label:

This is indeed after rebooting, so any desync from a fresh disklabel
would not be an issue. I've redone the /dev entries, and I am using
disklabel/newfs compiled from a sup(1) from yesterday.
And, regarding the le0 timeouts that have been mentioned, I am seeing
this timeout constantly. This machine (while I am setting up the SCSI
drive) has root over NFS, and I'm also telnetting. When I say, "constantly,"
I mean every few minutes. This timeout is definately an issue needing
resolution. I don't see the le0 timeout at all when using kernels from
a month ago or so in this same setup of netbooting and telnetting.
