Heyho!
(This is using kernel 2.6.31-rc3 as packaged by Debian)

ath5k can't connect to WLAN anymore.
syslog shows:

This only happens with bulk data transfers, and probably only when sending.
Downloading large dataset over WLAN is fine (I haven't tested it as much as
sending, though: downloads are mostly small, while the bulk sending happens
regularly during backup.)
It is not related to how long the WLAN is up: I can work for days or weeks
(happened with earlier kernels as well) with this laptop, over
suspend/resume, and WLAN works fine. It's only when I run backup that it
happens (always - but I since backups usually are incremental, they're often
small enough. But once I do a full backup WLAN goes down. So use cable for
those...)
Is this known? Can I get you more information?
Hardware is Acer AOA 150.
thanks

Working on it, can you please post the part when ath5k loads ?

I'm not sure if it helps, but if I:
load ath5k and let some stations associate (I'm testing virtual
STA logic)
.. wait a bit ...
rmmod ath5k; modprobe ath5k
then it fails to wakeup the MAC chip every time.
But, if I then wait a few seconds, and repeat the rmmod/modprobe commands, then it wakes
up and works fine.
I'm running a hacked kernel (and ath5k/wifi stack), so could be something
I'm doing wrong, but just maybe it will give you a reproducible test
case...
Thanks,
Ben

Yep, same here, same hardware.
I must say that moving large files typically results in prolonged
periods in which no communication is gone, maybe even something like
that.
