The freeze does NOT occur with the default 2.6.31.5 kernel (tested for > 6 hours with no freeze). The freeze does NOT occur with openSUSE-11.3 Milestone-7's 2.6.34 kernel (tested for > 12 hours with no freeze). The freeze does NOT occur if wired is plugged in with the 2.6.31.12-0.2 kernel. The freeze only occurs when wireless is plugged in with 2.6.31.12-0.2 kernel, within 20 minutes (sometimes within 10 seconds) of successful WLAN connection. Freeze is a freeze. Flashing caps lock. No response to any key press. No mouse movement. Only holding down power button for 10 seconds will switch OFF laptop integrated display. Wireless with the 2.6.31.12-0.2 will occur with 10 seconds to 20 minutes (random) after wireless is enabled/successfully-connected. There are no error message entries in the /var/log/messages, nor /var/log/Xorg.0.conf, nor dmesg, nor /home/oldcpu/.xsession-errors. Hardware is: 04:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection [8086:4235] Subsystem: Intel Corporation Device [8086:1121] Kernel driver in use: iwlagn Freeze occurs on 2.6.31.12-0.2 kernel-desktop with both radeonhd and fglrx graphic drivers (hence not believed to be driver related). Since freeze never occurs with wired connected, that also supports theory this is wireless related. Since freeze does NOT occur with 2.6.31.5 kernel, that supports theory this is kernel related to Intel PRO/Wireless 5300AGN. Error messages observed on <ALT><F10> konsole when freeze occurs with 2.6.31.12 notes a "kernel bug". Some screen images (in sequence) here of error messages when freeze occurs: 1st - http://www.imagebam.com/image/c2d84483668121 2nd - http://www.imagebam.com/image/6b153883668133 3rd - http://www.imagebam.com/image/de94da83668137 4th - http://www.imagebam.com/image/3bce2883668141 5th - http://www.imagebam.com/image/17728a83668153 6th - http://www.imagebam.com/image/1ce20483668157 Apologies for providing images that way, and for poor quality of images. This is VERY difficult to capture due to extremely rapid scroll of text on <ALT><F10>screen. Installation of compat-wireless-kmp-desktop version 2.6.34_2.6.31.05_0.1-2.1 and compat-wireless-scripts version 2.6.34-2.1 does not stop the freeze. While I flagged this as "Critical", in truth this is not urgent for me as I can survive on 2.6.31.5 kernel for wireless and 2.6.31.12 kernel for everything else (with a dual boot). I am concerned what ever was introduced by one of the two 2.6.31.12 kernels (or possible a kernel just before 2.6.31.12) could then be introduced by mistake in 2.6.34 kernel during an effort to be helpful to 2.6.34 kernel. Again, I note 11.3 milestone7 2.6.34 kernel works well from 64-bit KDE liveCD on this hardware. Reproducible: Always Steps to Reproduce: 1. boot to 2.6.31.12 kernel and enable wireless (with no wired connected) 2. 3. Actual Results: Always get a freeze at a random time, from 10 seconds to 20 minutes after the boot. Expected Results: No freeze is expected.
