Summary: S3 Resume hands on Acer Aspire 5652AWLMi
Product: ACPI
Version: 2.5
KernelVersion: 2.6.21-1.3228.fc7
Platform: All
OS/Version: Linux
Tree: Fedora
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Distribution: Fedora 7
Hardware Environment: Acer Aspire 5652AWLMi
Software Environment: Standard Fedora 7
Problem Description: After S3 Suspend (pm-suspend), resume will hang with blank
screen and no reaction on blind-typing "find /" (so system is really dead, no
screen problem). Will happen even when in runlevel 3 and even with
"init=/bin/bash" kernel option. Happens not only in Fedora, but happened in
Suse and Ubuntu, too, so i think, i can post it here since it will be a general
kernel problem. I've tried many different quirk-combination, but nothing
helped.
I've read about a debugging method using
echo 1 > /sys/power/pm_trace
pm-suspend
which gives the line
dmesg | grep "hash mat"
hash matches drivers/base/power/resume.c:70
so, resume_device_early seems to be the problem.
Steps to reproduce:
type "pm-suspend" on my notebook ;)
important fact: some times before, i used gentoo and with
"echo 3 > /proc/acpi/sleep" it was possible to suspend & resume....
