>Description:

Since updating from 5.99.22 I've been getting a lot of "fxp0: device
timeout" messages from the kernel, each accompanied by a couple
seconds' dropout of the network. This is a major pain because I use
this machine remotely a lot.

It only started happening just now after 3 days or so uptime.

tonnerre says he's been seeing the same thing and it takes some uptime
before it starts happening.

>How-To-Repeat:

boot, use network.

>Fix:

dunno. Anyone want to suggest things to try or changes to revert?
