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is no longer updated but using the keyboard/mouse does not work).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!
