I believe I was trying to switch from the GDM login console to a text console. Shortly after I tried to switch the machine froze up and I had to force power-off with the power button. This was in the log when I came back. ------------[ cut here ]------------ kernel BUG at drivers/gpu/drm/drm_crtc.c:530! invalid opcode: 0000 [#1] SMP Modules linked in: vhost_net vhost macvtap macvlan rfcomm fuse ccm xt_CHECKSUM ipt_MASQUERADE nf_nat_masquerade_ipv4 tun nf_conntrack_netbios_ns nf_conntrack_broadcast ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 xt_conntrack ebtable_nat ebtable_broute bridge stp llc ebtable_filter ebtables ip6table_nat nf_conntrack_ipv6 nf_defrag_ipv6 nf_nat_ipv6 ip6table_mangle ip6table_security ip6table_raw ip6table_filter ip6_tables iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack iptable_mangle iptable_security iptable_raw bnep arc4 pn544_mei mei_phy pn544 hci intel_rapl iosf_mbi nfc x86_pkg_temp_thermal coretemp dell_wmi dell_laptop iTCO_wdt sparse_keymap kvm_intel iTCO_vendor_support iwlmvm dcdbas kvm snd_hda_codec_realtek mac80211 snd_hda_codec_hdmi vfat snd_hda_codec_generic fat i8k snd_hda_intel snd_hda_controller snd_hda_codec crct10dif_pclmul snd_hwdep crc32_pclmul uvcvideo snd_seq iwlwifi videobuf2_vmalloc btusb ghash_clmulni_intel videobuf2_core snd_seq_device bluetooth videobuf2_memops cfg80211 snd_pcm i2c_i801 v4l2_common hid_multitouch videodev serio_raw media rtsx_pci_ms snd_timer rfkill tpm_tis memstick snd ie31200_edac mei_me soundcore lpc_ich mei edac_core shpchp tpm int3403_thermal dell_smo8800 int3402_thermal processor_thermal_device int3400_thermal int340x_thermal_zone acpi_thermal_rel nfsd auth_rpcgss nfs_acl lockd grace sunrpc btrfs xor nouveau i915 raid6_pq rtsx_pci_sdmmc mmc_core ttm i2c_algo_bit drm_kms_helper mxm_wmi drm crc32c_intel rtsx_pci mfd_core video wmi CPU: 0 PID: 857 Comm: systemd-logind Not tainted 4.0.0-0.rc4.git0.1.fc22.x86_64 #1 Hardware name: Dell Inc.

This bug affects me as well. I use vanilla 3.19.3 kernel on Debian. For me, it happens when I log out. At this point, X server should restart, but instead the machine hangs.

Looks like this commit is relevant: http://cgit.freedesktop.org/drm-intel/commit/?h=drm-intel-fixes&id=8218c3f4df3bb1c637c17552405039a6dd3c1ee1
(In reply to Evgeny Kapun from comment #3) > Looks like this commit is relevant: > > http://cgit.freedesktop.org/drm-intel/commit/?h=drm-intel- > fixes&id=8218c3f4df3bb1c637c17552405039a6dd3c1ee1 I confirm this fixed the problem for me. (patched against 3.19.3 vanilla) The bug can be triggered at boot time by GDM 3.16 (Wayland mode), or at shutdown.
Also http://mid.gmane.org/551A449B.8020300@intel.com This is fixed upstream, and the relevant commit is cc: stable, i.e. should find its way to some v3.19.y. Closing, thanks for the report.
Hi! I'm using Archlinux with GNOME 3.16 and also run into this issue. I applied this patch to my self compiled kernel (release 3.19.3) and it works. But occassionally the switching from GNOME (X11) to a specific TTY seems to hang *when multiple monitors* are connected. Steps to reproduce: 1. Repeated switching between GDM (TTY1, WAYLAND) and GNOME (first unoccupied TTY, X11) and a TTY managed by systemd to start getty. 2. At some point, switching from GNOME to a specific TTY isn't anymore possible Workaround: Switch to some other TTY, but not the specific TTY, which was originally desired. Now switching should be possible again. Maybe releated messages from dmesg: ...
