Hi Dave,
Not sure what happens, feel like memory corruption but not sure. the
contain of the command is totally bogus.
Could you please test and send update, it is part of "3.2+rc2+
Regressions from 3.0 and 3.1" reports
Thanks

Hi Dave,
Sorry for taking so long.
it is a bogus command from the firmware which driver try to process it
and cause problem. I am not sure how it happen. But could you please try
the patch I attach here.
For now I am just ignore the command, but not sure it is good enough,
might has to reload the firmware, but not sure.
Thanks

I can try the patch. Though FYI, I've not seen this bug again since I reported it.

no.

Will do.
Not sure if it's a helpful data point, but the access point is
an apple airport (in case that's sending something strange that
confused the firmware).

Are you seeing the problem without this patch? I guess the patch I done
here is not the right thing to do and I try to address the problem too
aggressively
Thanks

With Linus' current tree and this patch, I got a panic pretty quickly,
but with a different trace.

Agree, that is why I could not re-produce here after many try. Could you
share your configuration, such as band/channel, 32/64 bit system, 20/40
MHz, traffic type, open/security, power management, ...,

I've been running Linus' current tree for the whole time and haven't seen
any iwlwifi traces since my initial report on the 11th.
I can't reproduce the bug, even by doing the same operation
(an scp of a dozen photographs).
It seems to happen almost at random, as if it's somehow timing related.
I'm running the patched kernel again now, and it's been fine for the last hour.

Hi,
can you please that one ?
it solves a race in mac80211 (thanks to Johannes) ?
It should solved the annoying WARN_ON about the bad shape of the AGG
state machine.
Thanks

Hi
I looked again at your stack strace, we need more debug. Please enable
Rx debug flag: 0x1000000.
What is happening here is that the HW (the Flow Handler for instance),
is closing an empty RB (Receive Buffer). The beginning of the buffer
is 0x00005555 which is the maker of "End of Buffer" of the Flow
Handler. The marker helps the driver to understand that there is no
more useful data in the buffer.
So basically what we are seeing here is that the FH is sending an
empty buffer. Which is not nice.
This can very well be a bug in the read / write pointers in the Rx
flow, or something in that region.

This bug (or a related one) triggers on my laptop (Dell Latitude E6420)
since I switched from Kernel 3.0-debian to 3.1-debian (AMD64). I believe
that the bugs happens after waking up from the suspension-to-RAM.
Since I switched to 3.1 Kernel after waking up from suspension my laptop
freezes very often and I need to hard reboot it, this is really
annoying. This wasn't happening with 3.0 Kernel and I believe that
iwlagn is the cause.
I have an Intel Advanced-N 6205 (rev 34) wireless card.
The other day I was able to get the following kernel errors after waking
up from suspension with this 3.1 kernel[1]
This 3.1 Kernel is the Debian precompiled one (linux-image-3.1.0-1-amd64)
$ uname -r
3.1.0-1-amd64
[1] Find here the dmesg part that comes after the wakeup from suspension:
