Comment 5 Emmanuel Grumbach 2013-04-04 09:20:06 UTC 
I think I have an insight - can you please send try with debug=0x0010000f?
I would like to see the output.
Thanks
Comment 6 Stanislaw Gruszka 2013-04-11 08:49:56 UTC 
Please do

$ modprobe -r iwldvm
$ dmesg -c
$ modprobe iwlagn debug=0x0010000f
$ modprobe -r iwldvm
$ dmesg > dmesg.txt

And attach dmesg.txt here.
Comment 7 Stanislaw Gruszka 2013-04-11 08:50:28 UTC 
Please do

$ modprobe -r iwldvm

dmesg output as requested
Comment 9 Emmanuel Grumbach 2013-04-14 06:24:13 UTC 
the dmesg output doesn't include the SYSASSERT.
Comment 10 Stanislaw Gruszka 2013-04-16 12:09:18 UTC 
Ok, we need dmesg with SYSASSEDRT, new instructions:

$ modprobe -r iwldvm
$ dmesg -c
$ modprobe iwlwifi debug=0x0010000f

# reproduce the problem.

$ dmesg > dmesg.txt

Please check if "Microcode SW error detected" is there, and attach dmesg.txt file.

New dmesg output

This includes the "Microcode SW error detected" message followed by the kernel oops stack trace.

Patch from comment 12 and fix or it is currently applied on fedora kernel. Do you still can reproduce this issue on the latest 3.9 kernel ?
