Bug Description

After a high network load (it can be done in less than 30 secs), dmesg:
[ 722.502274] iwlagn: Microcode SW error detected. Restarting 0x82000000.
[ 724.714102] iwlagn: Can't stop Rx DMA.
[ 725.724929] iwlagn: No space for Tx
[ 725.724937] iwlagn: Error sending SENSITIVITY_CMD: enqueue_hcmd failed: -28
[ 725.724941] iwlagn: SENSITIVITY_CMD failed
[ 725.942810] Registered led device: iwl-phy0:radio
[ 725.942849] Registered led device: iwl-phy0:assoc
[ 725.942888] Registered led device: iwl-phy0:RX
[ 725.942923] Registered led device: iwl-phy0:TX

and the network is not working.
To renew a connection: service network restart, but when net load raises, that situation repeats.

It seems, that kernel-pae- detects SW error too, but restarts (something):
