Hi,
additional to the WARNING wireless with iwlwifi seems to be very flaky on 3.2.0-rc2.
Ping to the AP goes up to 4-5s in some periods (with network generally idle).
Here is some more info about the Hardware:
[ 11.133719] iwlwifi 0000:03:00.0: HW Revision ID = 0x35
[ 11.133825] iwlwifi 0000:03:00.0: irq 46 for MSI/MSI-X

If you need some more info, please don't hesitate to ask.
Best regards

Yeah I know about that one. I haven't found the time to look at it yet.
I do have a patch that can help to debug. This patch will be sent
through the regular channel.
I am considering to remove the warning though

Just after the warning there is "Queue stuck" message, without warning
there will be no hint what is causing firmware hung.

I applied the QUEUE_DEBUG.patch you posted in the other thread, not sure if I'm experiencing the same problem:

JFYI: I'm currently running on Linus git from Monday (last commit 4244cb482e8eab18142162a27c8829a04585863a)
for a while now and didn't have seen this Warning yet, nor did I experience the described lag.
Maybe some other patch might already have fixed it or at least lessen the probability for the
previous bug to occur.
Best regards
