I just tried it with 2.6.35 on my netbook, which has several updates from previous versions, but there still appears to be a few different problems, for example:

In the first case, the AP doesn't respond and things go crazy, and eventually the module is no longer able to figure out what precisely what rev the card is. 

$ grep 5100 first.txt 
... it all starts out so good ...
[    3.767200] iwlagn 0000:03:00.0: Detected Intel Wireless WiFi Link 5100AGN REV=0x54

... but then ...
[  137.305160] No probe response from AP 00:1f:90:e4:b0:2b after 500ms, disconnecting.
[  137.936179] iwlagn 0000:03:00.0: Error sending REPLY_RXON: time out after 500ms.
[  137.936198] iwlagn 0000:03:00.0: Error setting new RXON (-110)

... insanity happens ....
[  163.448208] iwlagn 0000:03:00.0: No space for Tx
[  163.448224] iwlagn 0000:03:00.0: Error sending REPLY_TX_POWER_DBM_CMD: enqueue_hcmd failed: -28

... more f the same ...
[  235.706723] iwlagn 0000:03:00.0: No space for Tx
[  235.706740] iwlagn 0000:03:00.0: Error sending REPLY_TX_POWER_DBM_CMD: enqueue_hcmd failed: -28
[  235.833120] iwlagn 0000:03:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0xFFFFFFFF

... and then...
[  241.318649] iwlagn 0000:03:00.0: Detected Intel Wireless WiFi Link 5100AGN REV=0xFFFFFFFF
[  241.321377] iwlagn 0000:03:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0xFFFFFFFF

In the second case, the queue gets repeatedly stuck "3 time"; then it reloads 

$ grep stuck second.txt 
... something bad happens ...
[   30.904063] iwlagn 0000:03:00.0: queue 4 stuck 3 time. Fw reload.

... and then it reloads ...
[   30.905730] iwlagn 0000:03:00.0: On demand firmware reload

and again, and again, and again....
[   38.456114] iwlagn 0000:03:00.0: queue 4 stuck 3 time. Fw reload.
[   38.457732] iwlagn 0000:03:00.0: On demand firmware reload
[   62.876130] iwlagn 0000:03:00.0: queue 4 stuck 3 time. Fw reload.
[   62.877863] iwlagn 0000:03:00.0: On demand firmware reload
[  103.216067] iwlagn 0000:03:00.0: queue 4 stuck 3 time. Fw reload.
[  103.219246] iwlagn 0000:03:00.0: On demand firmware reload

... but luck runs out eventually and then the "mac" goes into deep sleep.
[  260.768128] iwlagn 0000:03:00.0: queue 4 stuck 3 time. Fw reload. 
[  260.768146] iwlagn 0000:03:00.0: On demand firmware reload
[  260.772090] iwlagn 0000:03:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0xFFFFFFFF
[  260.772090] iwlagn 0000:03:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0xFFFFFFFF

> I have a Lenovo ThinkPad X200 which equipped with Intel PRO/Wireless 5100 AGN adapter.  When running Ubuntu 10.04 for a while, say 15 minutes or longer, the adapter cannot transmit data or even cannot reconnect to the router when it was disconnected.  My dd-wrt router shows that there are some errors when the data is transmitting.
