Ethernet bug in Linux 3.8.2 ( maybe in 3.8.x-3.8.2)


Created this post to warn anyone attempting to upgrade the kernel to 3.8.2 with a network card of model " Intel Corporation 82579LM". I've upgraded the kernel to 3.8.2 and encountered a silly bug. I cannot connect to internet via ethernet anymore (only if I do a cold reboot with the cable plugged). So, if I hibernate or go into sleep mode and then resume, the ethernet connection cannot be established. Same symptom if I unplug the cable and the replug it.

So, I found this:

Doing that hack works. The wireless connection is however not affected, it works as before.

There are also wireless bugs that prevent WiFi from working at all. Therefore I'm still using 3.7.10.

Thanks for the heads-up. I have an e1000e card too. Thankfully it's a desktop not a laptop, so I don't as a rule unplug the cable or use suspend so it's not impacting on me.

Unfortunately the 3.7 series is now EOL'd, so if 3.8.3 isn't of decent quality it might be necessary to go back to the 3.4 or even 3.2 series when the next upstream security issue forces people to move on.

Seems fine on slack64-current here. My kernel config is based on Pat's 3.7.1 huge kernel in current.

Perhaps it's actually an ACPI issue?

Maybe it depends on what power management features you've configured in the kernel.

Anyway, Patch here for those who can't wait:
( I've not tried it - I can wait )
