Qube2 problems with recent release-5 kernel

[Andy Ruhl <acruhl%gmail.com@localhost>]

Hello all,

I've come across a problem with my Qube2 that I'm not sure is a
hardware problem or NetBSD problem.

Here is the kernel:

# uname -a
NetBSD taz-dmz 5.0_STABLE NetBSD 5.0_STABLE (TAZ.SEP30) #0: Wed Sep 30 05:02:31
MST 2009  root@foghorn:/usr/obj-cobalt/sys/arch/cobalt/compile/TAZ.SEP30 cobalt

I netboot a Linksys NSLU2 from the Qube, and I noticed that it stopped
working after I built a new kernel from release-5 at some point. I'm
not sure what point, I don't take notes on this type of thing.

Anyway, it appears that dhcpd stopped responding to requests on the
network, and I noticed a lot of errors like this in /var/log/messages:

Sep 30 18:00:06 taz-dmz /netbsd: tlp0: receive error: CRC error
Sep 30 18:00:06 taz-dmz /netbsd: tlp0: receive error: MII error
Sep 30 18:00:06 taz-dmz /netbsd: tlp0: receive error: CRC error
Sep 30 18:00:21 taz-dmz /netbsd: tlp0: receive error: MII error
Sep 30 18:00:21 taz-dmz /netbsd: tlp0: receive error: CRC error
Sep 30 18:00:51 taz-dmz /netbsd: tlp0: receive error: MII error
Sep 30 18:00:51 taz-dmz /netbsd: tlp0: receive error: CRC error
Sep 30 18:01:06 taz-dmz /netbsd: tlp0: receive error: MII error
Sep 30 18:01:06 taz-dmz /netbsd: tlp0: receive error: CRC error

I tried tlp0 and tlp1 (primary and secondary) and both returned this error.

There are a whole lot of these. I was using tail -f /var/log/messages
to see if dhcpd was responding, and it wasn't, instead I would get
these errors.

So I put an ex based card into the PCI slot which I had been using
before with good results, but now I can't get it to connect to the
outside world. I have no idea why. I get a link light on it, but no
ping to my gateway:

I noticed this in my dmesg which I think I've never seen before:

Anyway, I'm kinda stuck. It seems most network stuff works with tlp0
or tlp1, but dhcpd doesn't and that's something I need to work.

And ex0 is kinda nice to have, but now it doesn't work at all...

I'll try a current kernel to see if that helps.
