Summary: no video after resume (with and without kms) Product: ACPI Version: 2.5 Kernel Version: 2.6.31-rc1 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Power-Sleep-Wake AssignedTo: acpi_power-sleep-w...@kernel-bugs.osdl.org ReportedBy: bug-tr...@fisher-privat.net Regression: No Created an attachment (id=22215) --> (http://bugzilla.kernel.org/attachment.cgi?id=22215) dmesg It was tested with latest linux-2.6 git and drm-linux. To make clean test i used test_suspend=mem with acpi_sleep options (s3_bios and/or s3_mode) and without acpi_sleep. Any acpi_sleep option will make my PC freeze. Without acpi_sleep it will resume but with black screen and i can access it with ssh. Disabling kms will resume with black console but Xorg will enable video. After resume dmesg has two traces, memory corruption and warn_slowpath_common: [ 60.816159] Corrupted low memory at ffff880000004200 (4200 phys) = 00420301 [ 60.816163] ------------[ cut here ]------------ [ 60.816169] WARNING: at arch/x86/kernel/check.c:134 check_for_bios_corruption+0xe4/0xf0() [ 60.816171] Hardware name: [ 60.816172] Memory corruption detected in low memory [ 60.816173] Modules linked in: binfmt_misc kvm_intel kvm snd_hda_codec_intelhdmi snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_timer snd_seq_device psmouse snd iTCO_wdt iTCO_vendor_support serio_raw soundcore snd_page_alloc e1000e [ 60.816190] Pid: 9, comm: events/0 Tainted: G W 2.6.31-rc1-25446-g1ae8c0a #1 [ 60.816192] Call Trace: [ 60.816196] [<ffffffff8104a8e8>] warn_slowpath_common+0x78/0xb0 [ 60.816198] [<ffffffff8104a97c>] warn_slowpath_fmt+0x3c/0x40 [ 60.816200] [<ffffffff8102aff4>] check_for_bios_corruption+0xe4/0xf0 [ 60.816202] [<ffffffff8102b000>] ? check_corruption+0x0/0x30 [ 60.816204] [<ffffffff8102b009>] check_corruption+0x9/0x30 [ 60.816206] [<ffffffff8105e4d4>] worker_thread+0x144/0x260 [ 60.816209] [<ffffffff810635c0>] ? autoremove_wake_function+0x0/0x40 [ 60.816211] [<ffffffff8105e390>] ? worker_thread+0x0/0x260 [ 60.816213] [<ffffffff810631e6>] kthread+0x96/0xa0 [ 60.816215] [<ffffffff8100c69a>] child_rip+0xa/0x20 [ 60.816217] [<ffffffff81063150>] ? kthread+0x0/0xa0 [ 60.816219] [<ffffffff8100c690>] ? child_rip+0x0/0x20 [ 60.816220] ---[ end trace e934ad520ce5f9cf ]--- [ 11.621573] PM: resume devices took 5.784 seconds [ 11.621574] ------------[ cut here ]------------ [ 11.621579] WARNING: at kernel/power/suspend_test.c:52 suspend_test_finish+0x7c/0x80() [ 11.621580] Hardware name: [ 11.621580] Component: resume devices [ 11.621581] Modules linked in: [ 11.621583] Pid: 1, comm: swapper Not tainted 2.6.31-rc1-25446-g1ae8c0a #1 [ 11.621585] Call Trace: [ 11.621589] [<ffffffff8104a8e8>] warn_slowpath_common+0x78/0xb0 [ 11.621590] [<ffffffff8104a97c>] warn_slowpath_fmt+0x3c/0x40 [ 11.621592] [<ffffffff8107ce7c>] suspend_test_finish+0x7c/0x80 [ 11.621594] [<ffffffff8107cac1>] suspend_devices_and_enter+0xb1/0x210 [ 11.621595] [<ffffffff8107cd4a>] enter_state+0x12a/0x150 [ 11.621598] [<ffffffff81377843>] ? rtc_time_to_tm+0xe3/0x1a0 [ 11.621600] [<ffffffff8107cd8d>] pm_suspend+0x1d/0x30 [ 11.621603] [<ffffffff81748f83>] test_suspend+0x140/0x1a7 [ 11.621605] [<ffffffff81748e43>] ? test_suspend+0x0/0x1a7 [ 11.621608] [<ffffffff8100905b>] do_one_initcall+0x4b/0x190 [ 11.621610] [<ffffffff8109d802>] ? register_irq_proc+0xe2/0x110 [ 11.621613] [<ffffffff81140000>] ? load_elf_binary+0x1b0/0x1fe0 [ 11.621616] [<ffffffff817346ef>] kernel_init+0x169/0x1bf [ 11.621618] [<ffffffff8100c69a>] child_rip+0xa/0x20 [ 11.621619] [<ffffffff81734586>] ? kernel_init+0x0/0x1bf [ 11.621621] [<ffffffff8100c690>] ? child_rip+0x0/0x20 [ 11.621622] ---[ end trace e934ad520ce5f9ce ]--- -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
