Michal, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command in the development release from a Terminal (Applications->Accessories->Terminal) as it will automatically gather and attach updated debug information to this report.
apport-collect -p linux <BUGNUMBER> Additionally, if you could try to reproduce this with the upstream mainline kernel that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Description changed: - System freezes on resume (sometimes on 2nd, 3rd... suspend/resume cycle). It seems to be a race condition related to Intel Idle Driver. Using the boot GRUB parameter "intel_idle.max_cstate=0" which disables the new Intel Idle Driver and assures fallback to ACPI idle, the problem disappears. Another, less clean, workaround was to completely disable Intel SpeedStep in BIOS. + System freezes on resume (sometimes on 2nd, 3rd... suspend/resume + cycle). It seems to be a race condition related to Intel Idle Driver. + Same problem confirmed on both Ubuntu 2.6.35 and 2.6.36 series kernels as well as corresponding mainline kernels. Brief testing on 2.6.32, 2.6.33 and 2.6.34 kernels led to same resume freezes; on Lucid 2.6.32 kernel it *seemed* that disabling "/usr/lib/pm-utils/sleep.d/94cpufreq" script has helped to avoid the race condition on resume. Note: the race condition only appears when resuming the laptop (Dell e6410) on battery power. Thanks to Mario Limonciello from Dell Linux engineering for hinting that Intel Idle Driver might be the element playing the determining role in this S3 resume race condition. + + WORKAROUND: Using the boot GRUB parameter "intel_idle.max_cstate=0" which disables the new Intel Idle Driver and assures fallback to ACPI idle, the problem disappears. + WORKAROUND: Disable Intel SpeedStep in BIOS.
