Comment 20 for bug 412704

I've tried the whole thing on 2.6.30.5:

I scp'd something to another computer. The first two times, it worked flawlessly, but the third time the following appeared:
[ 314.757531] iwlagn 000:0c:00.0: iwl_tx_agg_start on ra = 00:1f:3f:d4:e8:c9 tid = 0
[ 314.757595] iwlagn 000:0c:00.0: HW queue is empty

I scp'd again, this time:
[ 395.230500] iwlagn 000:0c:00.0: Microcode SW error detected. Restarting 0x92000000.

Then, wifi was down. Pinging a computer in my network resulted in:
[ 541.806238] iwlagn 000:0c:00.0: Invalid station for AGG tid 0
[ 541.807424] iwlagn 000:0c:00.0: Invalid station for AGG tid 0
[ 541.828119] iwlagn 000:0c:00.0: mac90211-phy0: failed to remove key (0, 00:1f:3f:d4:e8:c9) from hardware (-22)

After a minute, wifi was back.

Note that on 2.6.30.5, the computer did post that message but not freeze.

In 2.6.29, there is no error at all, so I suspect this to be a regression.
