Summary: i915 drm module: suspend to ram works only if invoked
after resuming from suspend to disk
Product: DRI
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: minor
Priority: medium
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Jesse Barnes pointed me here. This problem seem to be related to i915 drm
module.
I described and discussed the problem here:
http://lists.freedesktop.org/archives/pm-utils/2008-October/001673.html
I'm running debian lenny on an acer travelmate 290 with 855gm intel integrated
video (debian stock kernel 2.6.26-1-686, Xorg: 7.3, intel driver 2.3.2)
Description of the problem:
Suspend to disk always works.
When using console (no X running) or X with vesa driver:
- suspend to ram works fine
When using intel driver:
- suspend to ram fails on every normal boot: laptop suspends but on resume
system freezes with blank screen and no keyboard control
- suspend to ram works fine when resuming from disk: on a normal boot I invoke
pm-hibernate; laptop suspends to disk; when I resume from disk suspend to ram
works flawlessly every time I want
So the problem must be related to intel hardware. I was asked to produce a dump
using intel_reg_dumper here:
http://lists.freedesktop.org/archives/pm-utils/2008-October/001708.html
and to file a bug in bugzilla.
Many thanks for your help,
leonardo
