Package: src:linux Version: 4.3.3-5 Severity: normal Dear Maintainer,
I am experiencing frequent lockups on my laptop using linux-image-4.3.0-1-amd64 (though I already experienced the same problem with earlier kernel versions). The problem seems to be triggered only when using WiFi, and more specifically when using the eduroam network <https://en.wikipedia.org/wiki/Eduroam> -- I do not have the problem when using a home WPA network. Logs of the errors encountered (from syslog) are attached. Though some are in the graphical stack, I would suspect that the problem is caused by the WiFi driver rtl8723au. In particular log0 seems to be about this driver, and log1 is specific to wpa_supplicant. The problem often occurs a few seconds/minutes after associating to the eduroam network, in which cases the display freezes (sometimes partially, e.g., display is no longer updated but using the keyboard/mouse does not work). Magic SysRq sometimes works and sometimes doesn't. Sadly I am not aware of a way to reproduce the crash reliably. Please ignore the "Unknown key pressed" spam in the Kernel log below, which is caused by another issue <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1227996>. Thanks! -- Antoine Amarilli -- Package-specific info: ** Version: Linux version 4.3.0-1-amd64 (debian-ker...@lists.debian.org) (gcc version 5.3.1 20160101 (Debian 5.3.1-5) ) #1 SMP Debian 4.3.3-5 (2016-01-04) ** Command line: BOOT_IMAGE=/boot/vmlinuz-4.3.0-1-amd64 root=UUID=e3b76e5e-ee21-46dd-b5e2-a4b17f0a00b0 ro cgroup_enable=memory i915.enable_execlists=0 resume=UUID=fbf08c76-a232-4d9a-8d4e-70032070617a ** Tainted: C (1024) * Module from drivers/staging has been loaded. ** Kernel log: [ 881.574297] atkbd serio0: Unknown key pressed (translated set 2, code 0xbe on isa0060/serio0).
