Possibly because of the frequent renegotiating my iwl4965 card has
been making, it has now decided it's not going to pass packets
reliably until presumably next time I reboot.
I've noticed messages in syslog that I hadn't seen when things were
working fine. The problem possibly has only surfaced after rmmodding
the iwl4965 module, then remodding it. It stays with me through being
removed and modprobed again. It is being bonded in conjunction with a
physical ethernet, if that is relevant, although I think I reproduced
it when it was on its lonesome.

What kernel version is this?
Is this a regression from an earlier kenrel version? If so, which?

kernel 2.6.24
version 4.44.1.20 of the firmware.
The iwl4965 version is fairly ancient in mainline kernel: 1.1.17kds
Last time I looked, 1.2.24 was the latest version, but I never succeeded
in getting it to work (or compile?) in 2.6.24.
Don't know whether it's a regression - I've only been excercising my
wireless recently, although I'm sure I would have come across it before
when I was using 2.6.23 (which also comes version 0.1.15kds of the iwl4965
module, by the looks of it). Haven't rebooted yet since this problem
began, just in case this is just a temporary problem that needs debugging.

Can't say anything about that.

I've seen that before on other hardware but so far haven't managed to
track it down or even reliably reproduce it.

You can use the latest iwlwifi driver with kernel 2.6.24 when using the
compat-wireless project (http://linuxwireless.org/en/users/Download).
You can also load the driver with debugging (modprobe iwl4965
debug=0x43fff) to get more info about what happens during module unload.
