Hello all,
Oh the irony, I was just starting an email saying wifi is almost
unusable for me with 3.8 and my machine (a thinkpad t530) completely
froze while typing it...
I was going to say I'm getting a lot of:
iwlwifi 0000:03:00.0: fail to flush all tx fifo queues
with this device:
03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e)
Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN
Kernel driver in use: iwlwifi
But now I will be able to give you links to the actual soft lockup:

The same machine works perfectly fine with a vanilla 3.7. On 3.8,
before the machine froze I could see my download speed going up and down
like crazy (that's what prompted the "almost unusable" comment, it's so
painful loading a web page feels like being on dialup).
A rough text version is a follow:
BUG: soft lockup - CPU#1 stuck for 23s!
[...]
Call Trace:
iwl_trans_pcie_stop_device+0x15c/0x1c0 [iwlwifi]
iwl_down+0x1fd/0x300 [iwldvm]
iwlagn_prepare_restart+0x4f/0xd0 [iwldvm]
? idle_balance+0x110/0x2f0
iwl_bg_restart+0x52/0xe0 [iwldvm]
process_one_work+0x147/0x490
? iwl_op_mode_dvm_start+0xa50/0xa50 [iwldvm]
[...]
After that I the whole thing was frozen: keyboard/mouse would still work
but no IO would go whatsoever (even disk)...
The "fail to flush all tx fifo queues" are easy to reproduce: I get that
by copying file around / downloading and browsing the web.
Let me know if I can help in any way (like decoding addresses).
Cheers,
