Source: linux Version: 3.16.0-4-amd64 Followup-For: Bug #773661 Dear Maintainer,
After having upgraded from wheezy to jessie, I also observe these error messages. It also seems to be cosmetic and to doesn't affect the stability of X. I find out that it might be related to this kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=79261 Thanks a lot. You'll find below the dmesg traces I have at every boot: [ 32.276469] WARNING: CPU: 0 PID: 1112 at /build/linux-CMiYW9/linux-3.16.7-ckt2/drivers/gpu/drm/i915/intel_display.c:953 ironlake_crtc_disable+0x90/0x910 [i915]() [ 32.276472] pipe_off wait timed out [ 32.276474] Modules linked in: ctr ccm pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) binfmt_misc bnep nfsd auth_rpcgss oid_registry nfs_acl nfs lockd fscache sunrpc uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core v4l2_common videodev media ecb btusb bluetooth intel_powerclamp 6lowpan_iphc coretemp kvm_intel kvm joydev crc32_pclmul ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul arc4 snd_hda_codec_hdmi glue_helper nouveau iwldvm ablk_helper mac80211 snd_hda_codec_realtek snd_hda_codec_generic cryptd mxm_wmi i915 iwlwifi ttm iTCO_wdt iTCO_vendor_support dell_wmi sparse_keymap snd_hda_intel snd_hda_controller cfg80211 snd_hda_codec snd_hwdep drm_kms_helper dell_laptop dcdbas snd_pcm psmouse snd_timer rfkill evdev shpchp drm snd serio_raw intel_ips soundcore i2c_algo_bit [ 32.276538] pcspkr i2c_i801 lpc_ich i2c_core dell_smo8800 mei_me mfd_core battery wmi mei video ac button acpi_cpufreq processor loop fuse parport_pc ppdev lp parport autofs4 ext4 crc16 mbcache jbd2 sg sr_mod sd_mod cdrom crc_t10dif crct10dif_generic hid_generic usbhid hid crct10dif_pclmul crct10dif_common xhci_hcd crc32c_intel ahci ehci_pci ehci_hcd libahci libata scsi_mod r8169 mii usbcore usb_common thermal fan thermal_sys [ 32.276583] CPU: 0 PID: 1112 Comm: Xorg Tainted: G O 3.16.0-4-amd64 #1 Debian 3.16.7-ckt2-1 [ 32.276585] Hardware name: Dell Inc.
