ifplugd/e1000 oops

ifplugd/e1000 oops

[Adam Goode]

Hi,

I'm using ifplugd to monitor the link beat and automatically bring up
or down the network interfaces on my laptop.

When I unplugged my cable today, I got an oops. When I plugged it back
in, nothing happened. (Normally it should beep and bring the interface
back up.) When I removed and inserted the e1000 module, I got a freeze.



Thanks,

Adam

I've got a report of a similar oops, also using ifplugd. User in question (on 
IRC) is complaining that this has been happening for all of 2.6, in late 2.5 
(hasn't pinpointed any specific version) and in 2.4 since about 2.4.23.

Unfortunately in his case, it dies processing interrupts, so he gets nothing 
on disk, and is reluctant to set up a serial console on his box. I've tried 
emulating it here, but as yet have had no luck in getting it to oops.

Note: He's using an Intel EEPro/100B in his box, though he has a spare 
(unused) Realtek 8029 in there as well.

BTW: Kernel & ifplugd versions might be useful.

It's ifplugd version 0.23-1 (Debian). Kernel version 2.6.6-rc1.

I have a serial console, so I can help however I can. My machine is a
ThinkPad X40, running without ACPI.
