Bug Description
My laptop has a BCM4401-B0 100Base-TX and it works ok. However, about once every 5 wake-ups from suspsend-to-ram, the network card is not "refreshing" itself. What I mean is that the ethernet can't connect, it's like the kernel does not properly reset the device and reload the driver after a wake up. Ifconfig eth0 up/down does not help, I need to restart the laptop to get eth0 back.
I can try rmmod the driver and modprobe it again if you tell me which one it is:
eugenia@inspiron:~$ lsmod
