NetBSD bricked my wm0?

Subject: NetBSD bricked my wm0?
From: Jonathan Perkin <jonathan%perkin.org.uk@localhost>
Date: Fri, 31 Oct 2008 20:57:03 +0000

So I built a new system today, based on SuperMicro C2SBX+.  This has an
onboard Intel 82566DM chip.

Initial boot probed wm0 ok, but IIRC had messages similar to

  wm0: PCI-Express bus 
  wm0: No EEPROM 
  wm0: unable to read Ethernet address 

and so was unuseable.  I continued anyway, installed a spare wm0 PCI card
(82541PI) so I could grab cvs and take a look.

However, after this I noticed that the onboard wm no longer probed,
looking further its PCI config data had been trashed.  It now probes as:

  vendor 0x0004 product 0x0005 (ethernet network, revision 0x02) at pci0 dev 25 
function 0 not configured

which is obviously broken.

I've tried restoring BIOS etc, but nothing helps, it just reminds me of
the recent bug in Linux where this chipset and the 82567 was bricked due
to bad writing of various parts of the EEPROM.

Is NetBSD doing the same?  Is there any chance of being able to rewrite
EEPROM and put the original data back?

I've attached dmesg and pcictl dump output, hopefully someone can make
sense of it and see which bits have been re-arranged.

In the meantime, users may want to exercise caution booting NetBSD on
similar systems, just in case this is not an isolated incident.

Thanks,
