Hi,
[lkml.org still broken --> no accurate mail header info possible...]
Just to ask the obvious:
I assume using /sys/bus/pci/rescan does not help once it's broken?
(since the machine comes up empty at initial-boot scan, too)
Also, you could try diffing lspci -vvxxx -s.... output
of working vs. "distorting" kernel version - perhaps some register setup
has been changed (e.g. due to power management improvements or some such),
which may encourage the card
to get a problematic/corrupt state.

Yup, that seems to be
rtl_eri_read() in ethernet/realtek/r8169.c
waiting on low condition of
RTL_R32(ERIAR) & ERIAR_FLAG;
