[Virtual-pkg-base-maintainers] Bug#812929: base: after wakeup from suspend warnings on tty: edp_panel_vdd_work [i915]

[Norbert Cielecki]

Package: base
Severity: normal

Dear Maintainer,

   * What led up to the situation?
   	I don't know - maybe lcd matrix exchange on a new one at asus
	service - but I don't think so…
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     	If the system reboots or I turn power on there is no problem,
	but if wakeups from suspend appears message(s) which example
	I've listed below.
   * What was the outcome of this action?
   	Suspend and wakeup several times causes rapidly increase the
	quantity of warnings until further work on tty is impossible.
   * What outcome did you expect instead?
   	I expect that somebody helps me in disappear these warnings or
	explanation what can I do or some patch (whatever)…
