2.6.7-rc3: waiting for eth0 to become free

[Felipe Alfaro Solana]

Hi!

On my laptop, when using a CardBus 3c59x-based NIC, I need to run
"cardctl eject" so the system won't freeze when resuming. "cardctl
eject" worked fine in 2.6.7-rc2-mm2, even when there were programs with
network sockets opened (for example, Evolution mantaining a connection
against an IMAP server): the card is ejected (well, not physically),
even when there are ESTABLISHED connections.

However, starting with 2.6.7-rc3, "cardctl eject" hangs if a program
holds any socket open. After a while the "unregister_netdevice: waiting
for eth0 to become free" message starts appearing on the kernel message
ring. The only apparent solution is killing that program, ejecting the
card from its slot and wait until 3c59x.o usage count reaches zero.

Can someone tell me what's going on here?
Thank you very much.
