[linux-wireless: sorry for the duplicate, I didn't use the correct
address for LKML, as this is my first LKML post from work]
Hello. My kernel is 2.6.27.6, and at work, I sit in a place with
unreliable wireless connection. The problematic piece of dmesg looks
like this:

The messages about "PCI INT A" are still a problem, because at this
time, the audio loops and the mouse is unresponsive (i.e., the system
locks up for a brief period of time, but eventually recovers). Here is

The messages you refer to are printed because a user space app
(wpa_supplicant or network manager) brings the wireless interface down
and up. Interrupts are disabled when interface is brought down and
reenabled when interface is brought up.
The unresponsiveness is due to a bug that was fixed recently. The
patches have been merged into wireless-testing repo and will be included
in 2.6.29. If you want to try
the individual patches, please try:

These individual patches don't apply to 2.6.27.6, so I installed
today's compat-wireless-2.6, and it seems to work. Thanks!
OTOH, are these patches a material for backporting into -stable?

We are not planning to do so, but you are welcome to.

Hi
I assume that this backtrace I've got with 2.6.28-rc7 is the same issue ?
(If I get it right - this issue will not be fixed in 2.6.28 and is delay for
2.6.29 ?))

Hmm - it was something like an hour after resume when the problem started,
Here is timed part of the same backtrace:
[65627.782972] wlan0: associate with AP 00:11:d8:da:65:40
[65627.785569] wlan0: RX ReassocResp from 00:11:d8:da:65:40 (capab=0x401
status=0 aid=8)
[65627.785576] wlan0: associated
[69541.209873] wlan0: No ProbeResp from current AP 00:11:d8:da:65:40 - assume
out of range
[69541.810104] iwl3945: Error sending REPLY_SCAN_CMD: time out after 500ms.
[69542.309861] iwl3945: Error sending REPLY_RXON_ASSOC: time out after 500ms.
The begging of my trace looked similar.
Should I open new bugzilla separately ?

If you can reproduce this, it sounds more like a firmware problem, so
Reinette is probably going to want you to enable firmware debugging in
the driver. Try removing the iwl3945 module with rmmod, then "modprobe
iwl3945 debug=0x43fff", reproduce this command timeout, and attach the
logs to whatever bug report you file.

Unfortunately I do not have a reproducing case and it happened just once on
Wednesday after resume.
But when (if) it will repeat I'll try to reinsert module with debug - I think
without this my bug is not resolvable right ?

Try it. In the worst case, your report will be closed as a duplicate
of something else :)
