Strange... compiled, 2.6.24 and 2.6.23 here and they are all
stopping with this:

b44: eth0: Link is up at 100 Mbps, full duplex.
b44: eth0: Flow control is off for TX and off for RX.

And it seems to keep waiting for something. The system isn't freezed
(as CTRL+ALT+DEL kills the running processes and correctly reboots the

With Debian's it is working.
With vanilla 2.6.25 and my config it just enters an infinite loop of
"b44: eth0: powering down PHY".
Can different GCC versions cause this? Can a bad .config file cause
