Message #145129
Re: [Bug 1513648] Re: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0)
The bug appeared after upgrade from Ubuntu 15.04 to 15.10 or possibly after
some refular update after that.
I have now upgraded to the lates BIOS (A16) but the problem remains. Should
I re-run something to report potentially updated files?
Below are the (this time two) "cut here" sections.
Kind regards,
Patrik

Title:
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled
(expected 1, found 0)
Status in linux package in Ubuntu:
Incomplete
Bug description:
A few seconds after boot I get this message in the log (and wifi does
not activate).
Many things still work, but the system acts a bit confused. Sometimes
it gets almost unsusable until reboot (and then there are more of
those "cut here" sections in the log).
Kind regards,
Patrik
