Red Hat Bugzilla – Bug 806112
RTL8111/8168B Ethernet NIC Stopped working with kernel update
Last modified: 2012-03-26 21:48:45 EDT
Description of problem:
After updating to kernel-3.2.10-3.fc16.x86_64 NetworkManager failed to find a network interface. ifconfig failed to find a device. I found the following in my 'messages' log:
Mar 22 05:29:45 frodo kernel: [ 34.521035] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
Mar 22 05:29:45 frodo kernel: [ 34.521071] r8169 0000:02:00.0: (unregistered net_device): Mem-Wr-Inval unavailable
Mar 22 05:29:45 frodo kernel: [ 34.521076] r8169 0000:02:00.0: (unregistered net_device): region #2 not an MMIO resource, aborting
Version-Release number of selected component (if applicable):
The bug is still present as of kernel-3.3.0-4.fc16.
Reverting to kernel-3.1.0-7.fc16.x86_64 fixes it.
On a system with the affected hardware (RTL8111/8168B Gigabit Ethernet NIC), upgrade to kernel 3.2.10-3.fc16.x86_64 or kernel-3.3.0-4.fc16.
Steps to Reproduce:
1. sudo yum update
No networking capability
I am retracting this bug report because 1) i cannot reproduce it with kernel-3.3 and 2) because I reproduced the bug with kernel-3.1. I suspect I have an intermittent hardware glitch. Although it still could be a software timing bug (e.g. a race condition), I am no longer sure...
