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....
please include the output from lspci also, please try with "acpi_sleep=s3_bios" if it has Intel graphics. Also, you can get /proc/acpi/sleep back with CONFIG_ACPI_PROCFS=y, let me know if that makes any difference.
Is this still an issue in Linux-2.6.22.stable?
Please reopen this bug if it's still present with kernel 2.6.22.
