On a Thinkpad T430 (complete dmesg in attachment) equipped with a Intel Centrino Ultimate-N 6300 wireless card I'm experiencing periodical hiccups (meaning that the system seems to freeze for a few tens of milliseconds, this is particularly evident when moving the mouse, typing or watching a video); it seems that the culprit is the wifi interface (i.e. if I switch it off or simply force it down using ifconfig, the problem goes away). In 7.0 I see a lot of "iwn0: Fatal firmware error" messages, and this is what is reported after enabling the debug mode:iwn0: fatal firmware error firmware error log: error type = "SYSASSERT" (0x00000005) program counter = 0x00002A9C source line = 0x000002C1 error data = 0x0000000000000000 branch link = 0x00002A7600002A76 interrupt link = 0x0000153200000000 time = 165These firmware crash reports cannot be made sense of without Intel proprietary information which we do not have access to. We will need to figure out which behaviour of the driver triggers this and then work our way out from there. So it would help to see more context from debug mode, such as whether state transitions ocurred (SCAN -> AUTH, and such) right before the crash. These messages also appear in /var/log/messages where they have timestamps which might help with correlating events. We might have to add some debugging code to the driver to obtain more information about this issue. But please send a complete debug log first. Cheers, Stefan
