           Summary: network device does not survive laptop suspend
    Kernel Version: 2.5.66
            Status: NEW
          Severity: high

Distribution: Debian Unstable
Hardware Environment: Dell Latitude CPxJ 650
Software Environment: ?
Problem Description: 

I suspended my laptop this morning to move it from home to work without having
to shhutdown everything. The laptop came nicely out of the suspend, except
for my Cardbus ethernet device.

Since i resumed the laptop it hangs around every 10 seconds for around 2
seconds. Everything hangs, from mouse movement, to audio playback, to
pinging. This is seen in syslog, in great numbers:

The module in question is loaded directly, 3c59x, and was not unloaded prior
to the suspend.
