Pavel Rojtberg, 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 confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number> If reproducible, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspend ? If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.3.13-rc6 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** No longer affects: compiz (Ubuntu) ** No longer affects: xorg (Ubuntu) ** Project changed: unity => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Tags removed: performance ** Tags added: needs-kernel-logs needs-upstream-testing regression-potential resume suspend -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/887993 Title: desktop sluggish after resume from suspend Status in “linux” package in Ubuntu: Incomplete Bug description: after resuming from suspend unity/ compiz feels like it renders much less frames per second. Moving windows around is very jerky as are the animations of the sidebar. While moving around a window the Xorg CPU utilization spikes to 48%, so its eating up one of my 2 cores. logging out and logging in again solves the problem. Switching to VTs however does not. furthermore I got this on my kernel log: Nov 9 11:51:32 deepblue kernel: [39839.124572] ------------[ cut here ]------------ Nov 9 11:51:32 deepblue kernel: [39839.124580] WARNING: at /build/buildd/linux-3.0.0/kernel/power/suspend_test.c:53 suspend_test_finish+0x89/0x90() Nov 9 11:51:32 deepblue kernel: [39839.124582] Hardware name: 2007FVG Nov 9 11:51:32 deepblue kernel: [39839.124584] Component: resume devices, time: 10812 Nov 9 11:51:32 deepblue kernel: [39839.124587] Modules linked in: bnep rfcomm parport_pc ppdev binfmt_misc joydev snd_hda_codec_analog pcmcia snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_seq_midi hdj_mod btusb arc4 bluetooth snd_rawmidi snd_seq_midi_event ath9k yenta_socket psmouse pcmcia_rsrc serio_raw pcmcia_core mac80211 ath9k_common snd_seq ath9k_hw thinkpad_acpi nvram nsc_ircc irda ath radeon snd_timer snd_seq_device crc_ccitt tpm_tis cfg80211 video snd ttm drm_kms_helper drm i2c_algo_bit soundcore snd_page_alloc lp parport usbhid hid ahci libahci xhci_hcd e1000e btrfs zlib_deflate libcrc32c Nov 9 11:51:32 deepblue kernel: [39839.124644] Pid: 20240, comm: pm-suspend Not tainted 3.0.0-13-generic #22-Ubuntu Nov 9 11:51:32 deepblue kernel: [39839.124646] Call Trace: Nov 9 11:51:32 deepblue kernel: [39839.124652] [<c1047982>] warn_slowpath_common+0x72/0xa0 Nov 9 11:51:32 deepblue kernel: [39839.124666] [<c1084af9>] ? suspend_test_finish+0x89/0x90 Nov 9 11:51:32 deepblue kernel: [39839.124670] [<c1084af9>] ? suspend_test_finish+0x89/0x90 Nov 9 11:51:32 deepblue kernel: [39839.124674] [<c1047a53>] warn_slowpath_fmt+0x33/0x40 Nov 9 11:51:32 deepblue kernel: [39839.124678] [<c1084af9>] suspend_test_finish+0x89/0x90 Nov 9 11:51:32 deepblue kernel: [39839.124681] [<c108483a>] suspend_devices_and_enter+0xba/0x180 Nov 9 11:51:32 deepblue kernel: [39839.124685] [<c10849fe>] enter_state+0xfe/0x130 Nov 9 11:51:32 deepblue kernel: [39839.124688] [<c1083f4a>] state_store+0x8a/0xc0 Nov 9 11:51:32 deepblue kernel: [39839.124692] [<c1083ec0>] ? pm_trace_dev_match_show+0x20/0x20 Nov 9 11:51:32 deepblue kernel: [39839.124697] [<c127eecb>] kobj_attr_store+0x1b/0x30 Nov 9 11:51:32 deepblue kernel: [39839.124702] [<c1185656>] sysfs_write_file+0xa6/0x100 Nov 9 11:51:32 deepblue kernel: [39839.124716] [<c112876f>] vfs_write+0x8f/0x160 Nov 9 11:51:32 deepblue kernel: [39839.124719] [<c11855b0>] ? sysfs_poll+0x80/0x80 Nov 9 11:51:32 deepblue kernel: [39839.124723] [<c1128a4d>] sys_write+0x3d/0x70 Nov 9 11:51:32 deepblue kernel: [39839.124727] [<c152cc24>] syscall_call+0x7/0xb Nov 9 11:51:32 deepblue kernel: [39839.124730] ---[ end trace 307b324cec6bf296 ]--- To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887993/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
