Hi all,

I was recently able to acquire an U10 with a broken hme0
interface. The problem manifests itself as "no carrier on
hme0 -link down or cable problem?" so the mb circuitry is
probably in good condition, probably cold solder or something.

I added a 3com 3c905b NIC into a pci slot and installed
a -current snapshot (1.5 ZA) into it. After installation,
I left it to run overnight pinging another machine with
ping -i 60 -s 2500, to see if it stays up. Well, it didn't.

Below is my dmesg & kgdb output:

Sometime at night, it barfed:

Another one today:


# ping -s 2500 -i 60 10.10.10.138

Is this somehow related to the UDMA problems I saw
mentioned on the mailing list archives, or to the
broken hme0 on this mb? I can provide stack traces
etc, if necessary.
