SMC nic mac lost after booting kernel-xen / xend
Last modified: 2010-06-22 14:53:09 EDT
Description of problem:
After booting kernel-xen and starting xend with a default config, my nic's mac
becomes locked to FF:FE:FF:FF:FF:FF. Booting back to non-xen kernel does not
help. The "broken" mac is still there, even when I PXE boot from bios.
The only way I have found to fix the problem is to remove and re-seat the nic.
I have a lab of 15 of the same machines all having this problem.
Version-Release number of selected component (if applicable):
SMC pci card model: SMC1255TX
SMC optional boot rom installed: SMC1255B-ROM V1.23
Almost every time. Fails to occur only rarely.
Steps to Reproduce:
1. Install said nic w/ optional boot rom (as eth0)
2. Boot kernel-xen
3. Reboot to non-xen kernel
MAC = FF:FE:FF:FF:FF:FF
MAC = <NORMAL MAC>
Computers are all Dell Optiplex GX280 "n" series
Bios revision A08
Note: On these machines the SMC pci is eth0 (built-in is eth1). The problem does
not occur with built-in nic (if pci is removed and built-in is used as eth0).
I'll be happy to ship one of these nics to someone, if desired.

I have a feeling this isn't a problem any more, since it's been quite for 3 years. Joshua, can you confirm that this is no longer an issue?
It is no longer a problem for me as I do not have any SMC1255TXs in service and have not for some time.
The only reporter of this bug is no longer affected by it. I'll close it out, if somebody comes across it and has the same issue, then they can feel free to reopen.
