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): kernel-3.2.10-3.fc16.x86_64 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. How reproducible: 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 2. reboot 3. curse Actual results: No networking capability Expected results: Network works Additional info:
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... Rich
