Title:
system hang after resume from standby with i915 in bionic
Status in linux package in Ubuntu:
Incomplete
Bug description:
I've upgraded my i7-2600 system (cpu with integrated i915) from ubuntu
16.04 x86_64 to 18.04.1 x86_64 using do-release-upgrade.
It works fine except hanging after resume from standby. The system
does to standby (suspend to ram) when idle automatically. When it text
console, it resumes fine from pm-suspend, but after switching to
graphics the system hangs (magic sysrq does not work either). The
problem occurs with 4.15.0-33-generic and is also present with
mainline 4.18.7.
kern.log ends with: "kernel: PM: suspend entry (deep)". When resuming
into text console first, I get
