[Intel-gfx] i915 problems with suspend to disk
Hi, On 3.6, I've got a problem with my video driver after resuming from suspend-to-disk: the lower part of the display flickers, rapidly but irregularly (think of a neon sign in a bad film noir), flicking between the correct display and... something else, it's hard to see what. Shutting the lid of the machine (to trigger a suspend-to-ram) and waking it up again fixes the flicker. In syslogs, I have nothing obvious on suspend, and this warning on resume: Oct 4 19:53:04 ruth kernel: [ 2892.184086] [ cut here ] Oct 4 19:53:04 ruth kernel: [ 2892.184114] WARNING: at drivers/gpu/drm/i915/intel_display.c:1225 intel_crtc_disable+0x52/0x86 [i915]() Oct 4 19:53:04 ruth kernel: [ 2892.184115] Hardware name: 0196CTO Oct 4 19:53:04 ruth kernel: [ 2892.184117] pipe B assertion failure (expected off, current on) Oct 4 19:53:04 ruth kernel: [ 2892.184188] Modules linked in: cpufreq_powersave cpufreq_userspace cpufreq_stats cpufreq_conservative rfcomm bnep binfmt_misc uinput nfsd auth_rpcgss nfs_acl nfs lockd fscache sunrpc ext4 jbd2 mbcache loop arc4 iwldvm mac80211 snd_hda_codec_hdmi snd_hda_codec_conexant coretemp i915 snd_hda_intel snd_hda_codec drm_kms_helper iwlwifi snd_hwdep snd_pcm snd_page_alloc joydev snd_seq snd_seq_device snd_timer kvm_intel drm i2c_algo_bit thinkpad_acpi acpi_cpufreq nvram btusb bluetooth kvm crc16 cfg80211 microcode psmouse evdev i2c_i801 video rfkill wmi mperf i2c_core snd battery ac processor soundcore button btrfs crc32c libcrc32c zlib_deflate sha256_generic ablk_helper cryptd aes_x86_64 aes_generic cbc dm_crypt dm_mod sd_mod crc_t10dif ums_realtek usb_storage uas thermal thermal_sys ahci libahci libata uhci_hcd scsi_mod ehci_hcd r8169 mii usbcore usb_common Oct 4 19:53:04 ruth kernel: [ 2892.184198] Pid: 4117, comm: kworker/u:3 Not tainted 3.6.0 #14 Oct 4 19:53:04 ruth kernel: [ 2892.184199] Call Trace: Oct 4 19:53:04 ruth kernel: [ 2892.184207] [8102bdc5] ? warn_slowpath_common+0x78/0x8c Oct 4 19:53:04 ruth kernel: [ 2892.184213] [8104afd3] ? async_schedule+0xc/0xc Oct 4 19:53:04 ruth kernel: [ 2892.184216] [8102be71] ? warn_slowpath_fmt+0x45/0x4a Oct 4 19:53:04 ruth kernel: [ 2892.184221] [8104afd3] ? async_schedule+0xc/0xc Oct 4 19:53:04 ruth kernel: [ 2892.184238] [a03fdae0] ? intel_crtc_disable+0x52/0x86 [i915] Oct 4 19:53:04 ruth kernel: [ 2892.184245] [a0273e47] ? drm_helper_disable_unused_functions+0xd0/0xfb [drm_kms_helper] Oct 4 19:53:04 ruth kernel: [ 2892.184250] [a027461e] ? drm_helper_resume_force_mode+0xf1/0xff [drm_kms_helper] Oct 4 19:53:04 ruth kernel: [ 2892.184254] [8104afd3] ? async_schedule+0xc/0xc Oct 4 19:53:04 ruth kernel: [ 2892.184264] [a03dc17f] ? i915_drm_thaw+0xd4/0x10b [i915] Oct 4 19:53:04 ruth kernel: [ 2892.184274] [a03dc4fc] ? i915_resume+0x3b/0x50 [i915] Oct 4 19:53:04 ruth kernel: [ 2892.184279] [81193f21] ? pci_legacy_resume+0x39/0x39 Oct 4 19:53:04 ruth kernel: [ 2892.184284] [812196f7] ? dpm_run_callback.isra.5+0x26/0x54 Oct 4 19:53:04 ruth kernel: [ 2892.184289] [81219fe1] ? device_resume+0xd0/0x110 Oct 4 19:53:04 ruth kernel: [ 2892.184292] [8121a035] ? async_resume+0x14/0x38 Oct 4 19:53:04 ruth kernel: [ 2892.184296] [8104b070] ? async_run_entry_fn+0x9d/0x175 Oct 4 19:53:04 ruth kernel: [ 2892.184300] [81041a1a] ? process_one_work+0x184/0x2a3 Oct 4 19:53:04 ruth kernel: [ 2892.184304] [810426f1] ? worker_thread+0x1fe/0x29f Oct 4 19:53:04 ruth kernel: [ 2892.184307] [810424f3] ? manage_workers+0x223/0x223 Oct 4 19:53:04 ruth kernel: [ 2892.184310] [810424f3] ? manage_workers+0x223/0x223 Oct 4 19:53:04 ruth kernel: [ 2892.184315] [81045adf] ? kthread+0x67/0x6f Oct 4 19:53:04 ruth kernel: [ 2892.184319] [812fe774] ? kernel_thread_helper+0x4/0x10 Oct 4 19:53:04 ruth kernel: [ 2892.184324] [81045a78] ? kthread_freezable_should_stop+0x3c/0x3c Oct 4 19:53:04 ruth kernel: [ 2892.184327] [812fe770] ? gs_change+0xb/0xb Oct 4 19:53:04 ruth kernel: [ 2892.184328] ---[ end trace 4e63ed9ed8ebc493 ]--- Hardware is a Lenovo Thinkpad Edge13, lspci says: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) aka 00:02.0 0300: 8086:2a42 (rev 07) Let me know if you need more information.

Before you do a bisect, can you try the drm-intel-fixes branch from http://cgit.freedesktop.org/~danvet/drm-intel or a bit more risky, latest upstream git? That contains a completely rewritten modeset code, which might fix this already. To fix the breakage on 3.6 I guess we need a bisect - at least I don't have any idea off-hand what could have gone wrong here. Thank you for the quick response. The drm-intel-fixes branch seems to have done the trick. No more flickering. I think we can call this one fixed.
