Ville, smells like something in either your or Sonika's link rate changes. Vladi, if you can do a git bisect, it would help to reach a swift resolution here. (In reply to Jani Nikula from comment #1) > Ville, smells like something in either your or Sonika's link rate changes. The warning smells like the DPCD is bogus. I guess the full DPCD dumper didn't materialize yet... Otherwise it seems like there's two other bugs being reported here (flicker and hard hang on reboot). Does the backtrace look like we could get there *without* doing a dpcd read? There's the /sys/kernel/debug/dri/0/<connector-name>/i915_dpcd file in at least nightly. I do not have i915_dpcd in that location. As said you need to run drm-intel-nightly to have that. You can get it from http://cgit.freedesktop.org/drm-intel new stuff, from kernel 4.2-rc1 [ 7342.930081] ------------[ cut here ]------------ [ 7342.930087] WARNING: CPU: 0 PID: 426 at drivers/gpu/drm/i915/intel_display.c:1362 hsw_disable_ips+0xe6/0x1f0() [ 7342.930089] plane A assertion failure (expected on, current off) [ 7342.930090] Modules linked in: sha256_generic hmac drbg ctr ccm usb_storage uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core v4l2_common videodev arc4 nls_iso8859_1 nls_cp437 x86_pkg_temp_thermal coretemp vfat fat pcspkr iwlmvm mac80211 snd_hda_codec_generic psmouse iTCO_wdt iTCO_vendor_support iwlwifi cfg80211 snd_hda_intel snd_hda_codec snd_hwdep snd_hda_core snd_pcm snd_timer snd soundcore tcp_bic vboxnetadp(O) vboxnetflt(O) vboxdrv(O) autofs4 [ 7342.930111] CPU: 0 PID: 426 Comm: X Tainted: G W O 4.2.0-rc1+ #14 [ 7342.930112] Hardware name: LENOVO 20BSCTO1WW/20BSCTO1WW, BIOS N14ET30W (1.08 ) 06/05/2015 [ 7342.930114] 0000000000000000 0000000000000552 ffffffff816fab4d ffffffff81945bd0 [ 7342.930116] ffffffff8105246e ffffffff81948a58 ffff880200000030 ffff8800c7263b38 [ 7342.930118] ffff8800c7263ae8 ffff8802232f0000 0000000000000246 0000000000000246 [ 7342.930120] Call Trace: [ 7342.930124] [<ffffffff816fab4d>] ? dump_stack+0x40/0x50 [ 7342.930127] [<ffffffff8105246e>] ? warn_slowpath_fmt+0x9e/0x100 [ 7342.930128] [<ffffffff814b53d6>] ? hsw_disable_ips+0xe6/0x1f0 [ 7342.930130] [<ffffffff814b5a99>] ? intel_crtc_disable_planes+0x79/0x170 [ 7342.930132] [<ffffffff814b68da>] ? __intel_set_mode+0xbba/0xdc0 [ 7342.930135] [<ffffffff8140f43f>] ? drm_atomic_helper_check_planes+0x3f/0x1b0 [ 7342.930136] [<ffffffff814be688>] ? intel_crtc_set_config+0x378/0x8a0 [ 7342.930139] [<ffffffff81424eb2>] ? drm_mode_set_config_internal+0x62/0x220 [ 7342.930141] [<ffffffff8142adf4>] ? drm_mode_setcrtc+0x244/0x6f0 [ 7342.930143] [<ffffffff8141868a>] ? drm_ioctl+0x15a/0x520 [ 7342.930145] [<ffffffff81184d9e>] ? vfs_read+0xae/0x270 [ 7342.930147] [<ffffffff8108868b>] ? vtime_user_enter+0xfb/0x1a0 [ 7342.930149] [<ffffffff811a2fde>] ?
