Alex Williams tells me it's a PIO read timeout.
(confirms my guess given what man page said)

Offending address is likely 0x0000000090807000.
Matches nicely with what /proc/iomem thinks:
...
90000000-97ffffff : PCI Bus 0000:20
  90800000-9080ffff : tg3
...

Now just need to hunt down the code that pokes at +0x7000.

thanks,
