Description Cia Watson 2010-05-11 03:36:21 UTC
Description of problem: On shutdown menu of desktop installation, there's no option to suspend or hibernate. Using Power Management under screensaver to suspend system when inactive results in message that the system failed to hibernate and another message that it failed to suspend. This is a desktop and not a laptop computer. Version-Release number of selected component (if applicable): kernel-2.6.32-19.el6.i686 How reproducible: see below. Steps to Reproduce: 1. Click on Power Management option under >system > preferences > screensaver 2. Select option to Put computer to sleep when inactive for (30 minutes) 3. Go away and return to find that while the screen blanked, there are 2 error messages. Actual results: 2 error messages displayed when return to computer and unblank screen: First one says: Power manager: sleep problem. your computer failed to hibernate. check the help file for common problems. Clicking on 'visit help page' brings up a non-existent web page. The 2nd error message is identical to the first, except it says the computer failed to suspend, instead of hibernate. Expected results: Computer shuts down / hibernates / suspends after specified period of time. Additional info:

Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion.
Comment 3 Matthew Garrett 2010-05-17 15:59:16 UTC
What does /sys/power/state contain on this machine?
Comment 4 Cia Watson 2010-05-21 03:31:01 UTC
Sorry I didn't check my gmail for a couple days. /sys/power/state contains: standby [only] on RHEL v6 beta. On Fedora 13 where hibernate works perfectly, it contains: standby disk
Comment 5 RHEL Product and Program Management 2010-07-15 14:28:12 UTC
This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. **
Comment 6 Matthew Garrett 2010-09-28 16:07:14 UTC
Do you still see this with the current kernel?
Comment 7 Cia Watson 2010-09-30 01:17:26 UTC
Short answer, yes I do still see this with the current kernel-2.6.32-44.2.el6.i686. The long answer is that there is an option to select hibernate when I shut down, but hibernate stopped working on Fedora (where it used to work) after I installed opensolaris with a zfs filesystem on the partition next to my swap partition. Given the theory that having a zfs partition made hibernate stop working, I created a swap file, rather than using the swap partition; for the rhelv6 beta2 install, and added it to my fstab and from the output in top it appears to be active. When I select hibernate it appears to attempt to work (the desktop disappears and the hard disk spins a bit) but then the desktop reappears again and it never hibernates. It looks like it wrote something to the swap, output from top: Swap: 4095992k total, 7836k used, 4088156k free, 62112k cached Whereas there was previously 0k used of the swap. Here's other output if you want it: cat /sys/power/state standby disk devkit-power --dump Daemon: daemon-version: 014 can-suspend: no can-hibernate yes on-battery: no on-low-battery: no lid-is-closed: no lid-is-present: no
Comment 8 Matthew Garrett 2010-09-30 02:25:12 UTC
Suspend to swapfile isn't supported.
Comment 9 Cia Watson 2010-09-30 15:16:02 UTC
Ok, if suspend to swapfile isn't supported I commented that line in fstab and uncommented /dev/sda2 as swap and did a swapoff and swapon /dev/sda2 and attempted the hibernate. It powered off ok, but it didn't resume to the desktop it just booted up as normal.
Comment 10 Matthew Garrett 2010-10-26 13:39:17 UTC
It's up to dracut to trigger the resume.

blkid -p -o udev /dev/sda2 ID_FS_LABEL=SWAP-sda2 ID_FS_LABEL_ENC=SWAP-sda2 ID_FS_UUID=8ecb1b4e-47d7-4a63-a328-bbd2c44f695a ID_FS_UUID_ENC=8ecb1b4e-47d7-4a63-a328-bbd2c44f695a ID_FS_VERSION=2 ID_FS_TYPE=swap ID_FS_USAGE=other ID_PART_TABLE_TYPE=dos fdisk -l /dev/sda Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000767ea Device Boot Start End Blocks Id System /dev/sda1 1 6375 51200000 83 Linux /dev/sda2 6375 6885 4096000 82 Linux swap / Solaris /dev/sda3 * 6886 25121 146480670 bf Solaris /dev/sda4 25122 60802 286601240 5 Extended /dev/sda5 25122 31496 51200000 83 Linux /dev/sda6 31497 34683 25599546 83 Linux /dev/sda7 34684 43801 73240303+ 83 Linux And fwiw, rhel v6 beta2 is on /dev/sda5.
Comment 13 Harald Hoyer 2010-10-27 09:11:22 UTC
Does it help, if you put "resume=LABEL=SWAP-sda2" on the kernel command line?
Comment 14 Cia Watson 2010-11-01 00:43:59 UTC
Short answer: No, and yes. Longer answer: with the partitioning scheme shown above, it didn't resume even after adding the resume= statement on the kernel line in the menu.lst file. As I wasn't really using OpenSolaris (sda3) anymore, and still suspecting that the Solaris (ZFS) filesystem was part of the problem, I made copies of important stuff then deleted the partition. It now looks like: fdisk -l /dev/sda Device Boot Start End Blocks Id System /dev/sda1 1 6375 51200000 83 Linux /dev/sda2 6375 6885 4096000 82 Linux swap / Solaris /dev/sda4 25122 60802 286601240 5 Extended /dev/sda5 25122 31496 51200000 83 Linux /dev/sda6 * 31497 34683 25599546 83 Linux /dev/sda7 34684 43801 73240303+ 83 Linux And now hibernate works just fine, with and without the resume= statement. I don't know if the proximity of the swap & Solaris partitions are what kept it from working or not. But now it's working, so feel free to close this bug report.
Comment 15 Harald Hoyer 2011-02-01 10:26:34 UTC
seems like the boot flag did the trick...
