http://bugzilla.novell.com/show_bug.cgi?id=502193 Summary: Xen kernel reports to be capable of suspend to RAM, but fails to do so Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: x86-64 OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: nice@titanic.nyme.hu QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; hu-HU; rv:1.9.0.9) Gecko/2009041500 SUSE/3.0.9-0.1.1 Firefox/3.0.9 I run this xen kernel: milleniumfalcon:~ # uname -r 2.6.27.21-0.1-xen milleniumfalcon:~ # cat /proc/cmdline root=/dev/disk/by-id/ata-HTS541010G9SA00_MP2ZX0XLG71D3S-part1 resume=/dev/disk/by-id/ata-HTS541010G9SA00_MP2ZX0XLG71D3S-part2 splash=silent vga=0x31a milleniumfalcon:~ # cat /sys/power/state mem So it reports that its capable of s2ram. KDE 4.2.3 displays the suspend to RAM button indeed (and not a suspend to disk button), but when I try to suspend to RAM by KDE GUI, the suspension process "bounces", that is, my X.org desktop disappears, the system seems to prepare for suspension, but instead of S3 state, the machin continues to run. X.org reappears, and I can work again. Using the s2ram (and s2disk, being curious) commandline utility is also unuccessful: milleniumfalcon:~ # s2ram Switching from vt7 to vt1 /proc/sys/kernel/acpi_video_flags does not exist; you need a kernel >=2.6.16. switching back to vt7 milleniumfalcon:~ # s2disk s2disk: Could not stat the resume device file. Reason: No such file or directory But when I do a 'echo mem > /sys/power/state', the system seem to reach the S3 state: display turns off, caps lock and num lock LEDS blink together once, all fans and drives stop working, and the power LED starts blinking slowly (this is how my Compaq nc6320 behaves during sleeping). However, when I try to wake it up now, the display remains turned off and the system is unaware of the keyboard (no caps lock feedback), however, fans, and HDD are running (HDD LED also indicates some activity). I have to turn it off forcibly. Reproducible: Always Steps to Reproduce: 1. Try to do a suspend (or maybe hibernate too) on a Xen kernel Actual Results: The attemt is either unsuccessful but harmless, or causes the system to hang. Expected Results: I don't know. Maybe Xen kernels shouldn even support suspend ( http://wiki.xensource.com/xenwiki/XenFaq#head-cb7861c9865fc8fbae3bb472f04c5d... ). Or should it ?
