[1.] panic when starting uml host with bridged networking on an Intel
82562 (e100 driver)
[2.] I'm running user-mode-linux on a Gigabyte GA-8IG1000MK
motherboard (Intel 865G chipset with onboard 82562 ethernet), and
experience repeatable kernel panics when starting a uml instance. I have
three bridges to the host (br0, br1 and br2) with the hosts eth0, eth1 and
eth2 as port 1 on each bridge, respectively. eth0 is a 3Com 3c595 (3c59x),
eth1 is the onboard Intel 82562 (e100), eth2 is a Netgear Natsemi
DP83815 (natsemi).
The panic does not occur if I do not plug the physical LAN cable into the
Intel 82562 ethernet port. 'Internal' networking works fine, the uml
instance and the host can communicate via the bridge (w/ lots of traffic:
ping -f), but when plugging in the cable the host kernel panics on the first
packet.
If I take the interface down within the uml (uml# ifconfig eth1 down) and
then plug in the the physical LAN, all works well *for a while*, though the
panic still occurs after some traffic has passed (about 60-100 pings).
The eepro100 driver works as expected (no panics).
