Probably the hibernation image is created successfully, but at wake-up, various forms of failure occur: blinking caps lock and scroll lock LEDs on keyboard, partial activation of X server, kernel panic, looping wake-up attemtps. This is a desktop computer. Motherboard is 64 bit, has Intel's I/OAT hardware. BIOS has an option to enable/disable it. By default, the acceleration is enabled. Also, during debugging attempts with various configurations, I encountered the already-submitted bug 851044. RAM is 16 GiB and swap partition is slightly larger. RAM and swap are practically empty (mostly free, but active) before hibernation attempt. Hibernation worked on the same computer with opensuse 12.3. However, removal of package "suspend" was required, which was erroneously installed by default on my desktop computer. Fails with no X server running, with su only logged in, at runlevel 3, and a few other conditions that I tested. See more on https://forums.opensuse.org/english/get-technical-help-here/install-boot-log... Reproducible: Always Steps to Reproduce: 1. Use a Gigabyte motherboard, opensuse 13.1 with kernels 3.11.6-4-desktop 64 bit and also with kernel 3.12.5. 2. Attempt to hibernate, and then wake up. Actual Results: Wake-up stops at some stage and the computer crashes. Sometimes it is possible to see messages at wake-up attempts. Files in /var/log/ do not contain helpful information. File pm-suspend.log indicates successful hibernation and pm-powersave.log is empty. Other files do not contain relevant information. Expected Results: Wake-up from hibernation with return to original tasks running. Once it was possible to see on the screen a message that indicated kernel BUG in file /usr/src/linux-3.11.6-4/drivers/dma/ioat/dma_v3.c, line 768. The message was not in log files which I could see after hard restart and it did not appear always. I could not capture that message. I don't have it. On the screen sometimes kernel panic information appears with trace reporting violation in ioat, dma, IRQ and timer. I could not capture that message and don't have it. I disabled Intel I/OAT in BIOS. Hibernation works now; tested for two days. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
