Folks,

I've got a DEC Prioris 6166 running NetBSD 1.4.1(ish) with a 3Com
3c905-TX (pci) card and a Novell NE3200 (eisa) card in it.  The
network is plain old 10Mbit UTP.

There doesn't seem to be support for the 3200 at the moment:

	wincen:~ 25> dmesg | grep 'unknown device'
	unknown device NVL0701 at eisa0 slot 2 not configured

The 3c905 is more-or-less ok except it gets a lot of output errors.
Here's some config info:

	wincen:~ 26> dmesg | egrep 'ex0|nsphy0'
	ex0 at pci0 dev 6 function 0: 3Com 3c905-TX 10/100 Ethernet
	ex0: interrupting at irq 14

Copying /netbsd (about 1.4MB) to an NFS mounted filesystem adds
about 1100 output packets, 80 output errors and 120 collisions every
time.  I've swapped cables, hub ports, etc with no improvement.
Using autoselect or manually selecting 10baseT makes no difference.
Unfortunately I can't pull the box apart, and I don't think I've got
any spare e/net cards anyways.  I've got another box with a 3c905B-TX,
and it works fine.

Two questions then:

 + Has anyone seen any behaviour like this before?  Could it be
   a faulty card?

 + Is support for the NE3200 forthcoming?

TIA,
Simon.
an do it's job even if you're working > with the RAID set. This isn't mentioned in the man page for raidctl. In the description of the -i option, it may pay to mention that this task can be backgrounded (with the appropriate warnings). /etc/rc support for autodetecting non-clean parity and starting a "raidctl -i" in the background would be way-cool - I'd play with this myself, but the only box I've got with RAIDframe is a production box, so this isn't an option :-( Simon.
