I get a rather big amount of 'b44 ssb1:0: eth0: powering down PHY' messages in 
dmesg shortly after booting:

# grep -c 'b44 ssb1:0: eth0: powering down PHY' /var/log/messages
124566
# grep -c 'b44 ssb1:0: eth0: late interrupt' /var/log/messages
1141

The same thing happens when resuming from suspend to RAM. This is accompanied 
by kworker/0:3 (?) taking 100% CPU time for 1 min or so. I'm running 2.6.35 
now, so I might be wrong about the name of the kernel thread.

Thanks,
