I was able to narrow this down a bit - the problem can be reproduced with
the ne2k-pci driver alone, sky2 is not needed.
Powering off isn't necessary, either.
Hardware preparation:
- eth0: Compex ReadyLink 2000 (BNC+TP), ne2k-pci driver,
network cable disconnected
How to reproduce the problem:
brctl addbr br0
brctl addif br0 eth0
ifconfig eth0 0 up
ifconfig br0 192.168.1.17 up
sync
find / >/dev/null &
ping -b 192.168.1.255
This will lock up my system, usually within a few seconds.
Some additional information:
- I could not reproduce the problem when using eth0 directly,
without a bridge.
- Booting with "maxcpus=1" does not help, the problem remains.
My system doesn't boot with "nosmp", otherwise I would have
tried this too.
