Description of problem:

Problem with r8169 NIC driver

Version-Release number of selected component (if applicable):

kernel-3.4.4-5.fc17.x86_64


How reproducible:

Install kernel-3.4.4-5.fc17.x86_64


Steps to Reproduce:
1. install or upgrade to FC17 on system with  RTL8168b/8111b
2. install kernel-3.4.4-5.fc17.x86_64

Did this just start with 3.4.4-5.fc17, or have you noticed it with previous kernels?

Can you attach the full dmesg for that boot please?

Full dmesg from boot
Comment 3 Łukasz Trąbiński 2012-07-13 13:42:22 UTC 
Previously we used kernel-2.6.43.8-1.fc15.x86_64 on FC15. Two days ago we done upgrade to FC17.

I meant the dmesg for the boot showing the issues in the original comment.  This seems to be a fresh reboot.  I was curious if there were other messages in dmesg pertaining to the eth0 device other than just the link up ones.

OK, here is full dmesg from running system.

Hi
I have just changed kernel to  3.4.6-2.fc17.x86_64, and after 30 minutes I got Ooops. I don't know that is related with NIC flap but I send it here, maybe it can by helpful for future debugging.

Comment 7 Łukasz Trąbiński 2012-09-07 08:51:36 UTC 
Hi
With kernel 3.5.1-1.fc17.x86_64 ethernet card works ok without problems.

> With kernel 3.5.1-1.fc17.x86_64 ethernet card works ok without problems.

What link speed and duplex do you get? I just filed bug 855299 and it would be interesting to know if other people experience the same problem.
Comment 9 Łukasz Trąbiński 2012-09-07 09:46:51 UTC 
I had the same problem with older kernels like 3.4.4-5.fc17.x86_64

Now, with 3.5.1-1 it works ok.
