I have a PCI-E pro/1000 MT Quad Port adapter, which works quite well under 2.6.19.2 but fails to see link under 2.6.20-rc5. Earlier today I reported this to [email protected], but thought I should get the word out in case someone else is testing this kernel on this nic chipset.

Due to changes between 2.6.19.2 and 2.6.20, Intel driver 7.3.20 will not compile for 2.6.20, nor will the 2.6.19.2 in-tree driver.

<snip, worthless>
Affected chipset:
lspci -nn output (quad port):
09:00.0 Ethernet controller [0200]: Intel Corporation 82571EB Gigabit Ethernet Controller [8086:10a4] (rev 06)
lspci -nn output (dual port):
07:00.0 Ethernet controller [0200]: Intel Corporation 82571EB Gigabit Ethernet Controller [8086:105e] (rev 06)
<snip, readability>

From what I've been able to gather, other Intel Pro/1000 chipsets work fine in 2.6.20-rc5. If the e1000 guys need any assistance testing, I'll be more than happy to volunteer myself as a guinea pig for patches.

I wasn't aware that I was supposed to post this as a regression, so changed the subject, hoping that someone will pick this up and run with it. Primary issue being that link is not seen on this chipset under 2.6.20-rc5 via in-tree e1000 driver, despite multiple cycles of ifconfig $eth up && ethtool $eth | grep link && ifconfig $eth down. Tested on 2 machines with identical hardware.

I asked Allen to report this here. I'm working on the issue as we speak but for now I'll treat the link issue as a known regression once I confirm it. If others have seen it then I'd like to know ASAP of course ;)

Cheers,

Auke
