Description Allan Duncan 2010-04-28 03:16:22 UTC
Description of problem:

For at least the r8169 gigabit  controller the NetworkManager-0.8.0-6.git20100408
only recognises 100Mbit.  0.7.998-2.git20100106 worked fine. I can switch back to that and get gigabit back again.

Version-Release number of selected component (if applicable):
NetworkManager-0.8.0-6.git20100408 (and the -gnome and -glib parts)

How reproducible:
100% on toggling between versions

Steps to Reproduce:
1. Let yum update you to NetworkManager-0.8.0-6.git20100408
2. Reboot
3.Lose gigabit capability :-)
  
Actual results:


Expected results:


Additional info:

Kernel 2.6.33.1 PAE i686 compiled from from F13 source
Gigabyte MA78GM-S2H m/b (RTL8169 NIC)

The presence or absence of gigabit capability is indicated by the lights on the Netgear GS105E switch that the host is attached to, which presumably senses the presence of a cat6 physical connection.

The switch is recent, so I have no knowledge of the behaviour prior to 0.7.998-2.git20100106.

Comment 1 Allan Duncan 2010-04-29 12:45:39 UTC
I guessed at the NIC - it is really RTL8111c.
Watching the boot messages and the lights on the switch the cat6 capability switches on as a udev start message flashes up, and looking in the log that is where the r8169 driver is loaded.  Tracking back through old logs for that point doesn't show anything obviously different.

A new kernel 2.6.33.2-57 works with both versions.

Going back to the older kernel the damn thing now works with 0.8.0-6.git20100408, so the nice clean correlation with the two versions of NetworkManager is gone.
No other system changes have been made.

Gaarh!  Scrub this bug report then.

Ok, thanks for investigating.
