Hi

I have an Intel Atom D945GCLF based system. It has a realtek RTL8101E
PCI network interface.

With linux-2.6.27-rc4 - everything seems fine. I think we've been
working OK since 2.6.26ish.

With linux-2.6.27-rc5, "ifconfig eth0" just hangs. lspci -vvx reports,
00: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff

10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff

20: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff

30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff =20

Before I load the driver lspci -vvx looks OK.

I do not have (much) time to look into this any further but hopefully
this might help someone.

I know there are problems with this device on the atom board
particularly around warm start but thus far I seem to have avoided this
issue.

A cold start in this case does not help.

Lspci.bad comes from -rc5 with the r8169 driver loaded.
Lspci.good comes from -rc4 with the r8169 driver loaded

Cheers

John

did you check if falling back to the older kernel makes the device work again?

FWIW, these patches make the Ethernet card in the MSI Wind I've been recently
testing work much much more reliably. :-)

Thanks,
Rafael

I've only tried all of them at once.

Hmm, probably a lot of 0xff stored in NVRAM of the card? There seems to be 
some similarity to the problem that seemed to be e1000e-specific so far.

BTW does by any chance booting with 'nopat' kernel commandline parameter 
fix the problem?
