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: http://mathieu.csetco.com/iwlwifi/iwlwifi-oops1.jpeg http://mathieu.csetco.com/iwlwifi/iwlwifi-oops2.jpeg http://mathieu.csetco.com/iwlwifi/iwlwifi-oops3.jpeg 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).
