Subject: tg3 does not want to go up (config space problems).

Hi.

I've cought a problem with my laptop and tg3 driver.
Suddenly (it was turned off quite for a while) tg3 driver does not start
up.

Here is dmesg messages (copied by hand, some bits are ommitted):
acpi: ... // device enbaled in couple of words

eth0: Tigon3 [partno(BMC5705mA3) rev 3003 PHY(5705)] pci:33/32, 10/100

eth0: rxcsum[1] linkchgreg[0] miirq[0] asf[0] split[0] wirespeed[0]
tsocap[1]
eth0: dma_rwctrl[763f0000] dma_mask[64 bit]

PM: writing back config space on device /* tg3 device pcix id*/ at
offset b (was 165d14e4, writing 890103c)
offset 3 (was 0, writing 4010)
offset 2 (was 2000000, writing 2000003)
offset 1 (was 2b00000, writing 2b00006)
offset 0 (was 165d14e4, writing 165e14e4)

ADDRCONF(NETDEV_UP): eth0 link is not ready

This problem never happend before, but suddenly appeared after quite
long suspend to disk (several month I think).
Nothing was changed in hardware.
Both 2.6.18 and 2.6.21-rc3 have the same issue.
No interrupts reported in /proc/interrupts.

I have 2.6.21-rc3 source tree in laptop, so can apply patches by hand
reading them from main desktop, but can not (easily) install additional 
software.

Thanks.
