Re: Question about PCMCIA, APM and 3C3FE575CT

[David Brownell <david-b@pacbell.net>]

Hmm, seems like a bug of some kind in how something is
treating APM operations.  If the suspend takes the network
down, the resume is supposed to bring it back up.  I'd
guess that some "resume" path isn't doing something it's
expected to do.

What happens if you take the card out while it's suspended,
and plug it in later after the system is fully resumed?  If that
behaves differently, it's clear the resume path has a bug.
Do you see log messages reporting that the resume path
is bringin up the network interfaces?  (You might need to
enable debugging in the /sbin/hotplug script.)

Someone recently mentioned a problem on some distro
that the networking code was sometimes brought up
after the bus code (such as USB or Cardbus PCI).  That
sequence would cause trouble, since the request to bring
the network interface "up" would likely be ignored until
later, when the networking code was brought up.
