Red Hat Bugzilla – Bug 119279
kernel-2.6.4-1.290 reboots when leaving suspend mode
Last modified: 2007-11-30 17:10:39 EST
kernel-2.6.4-1.290 on hardware that has incomplete support for ACPI; therefore using apm (apmd-3.0.2-20). Sharp notebook PC-AR50. Kernel boot arguments ro acpi=off psmouse.proto=imps root=LABEL=/ rhgb The notebook suspends normally when closing the lid. When opening the lid the BIOS prompts for the password and when given the machine seems to exit suspend (eg. HD noises), and immediately reboots. When booting the ext3 filesystems are recovered and the logs indicate the machine was not cleanly shut down. Version-Release number of selected component (if applicable): happens with kernel-2.6.4-1.290 does not happen with kernel-2.6.1-1.65 How reproducible: every time with the affected kernel on my hardware Steps to Reproduce: 1. boot affected kernel 2. enter suspend mode 3. attempt to exit suspend mode Actual results: affected kernel reboots the machine Expected results: normal exit from suspend Additional info: I will do any reasonable testing to attempt to diagnose this bug or test patches/fixes.
I have also had this same problem, but with more than the recent kernel. I have seen this with any of the 2.6.x kernel I have used (both vanilla and redhat / fedora) Upon un-suspend the system does one of two things 1) Reboots 2) hangs In the case of a reboot, suspending from a pure console it is possible to see that the system seems to come out of sleeping, display the old contents of the console and THAN reboot suddenly. Also doing some general prusing this may be related to some changes that happened in the 2.5.x kernel related to the pci setup and it being lost. From those comments it looked like we might be SOL :-( If there is anything I can do to help with this, let me know as I really want my laptop to suspend / resume properly! - John H.

Confirming http://www.redhat.com/archives/fedora-test-list/2004-March/msg00554.html , as APM suspend last functioned OK with 2.6.3-1.52 (Dave Jones' kernel), failed on all RH kernels after that one (4G/4G merge ?). Symptoms : when resuming after a successful APM suspend, there is some harddisk activity (nothing gets logged to syslog), and the laptop (IBM ThinkPad A30p) reboots. As ACPI sleep (S3) never worked in the past, I'm eagerly awaiting an RPM with 2.6.5-rc2-mm4 ACPI 4G/4G sleep fixes.
unfortionately those are included already but aren't sufficient ;(
Additional note : with 2.6.4-1.279, I once (out of approx. 3 or 4 tests) got a kernel OOPS in the ext3 module, immediately following the APM resume ; nothing was written to syslog, though, and the machine immediately rebooted thereafter, so no additional info (don't have a serial console neither).
