** Description changed: My guest machine has Xubuntu 14.04.3 LTS installed and uses autologin. It boots successfully but if I try to log off and then log on into another account, during loggin on some crash happens and it goes back to lightdm. In syslog I found the following: Sep 9 23:24:56 desktop spice-vdagentd: opening vdagent virtio channel Sep 9 23:24:56 desktop kernel: [ 2640.545517] input: spice vdagent tablet as /devices/virtual/input/input7 Sep 9 23:25:55 desktop kernel: [ 2700.313900] ------------[ cut here ]------------ Sep 9 23:25:55 desktop kernel: [ 2700.313923] WARNING: CPU: 0 PID: 1200 at /build/linux-lts-vivid-BZwsXG/linux-lts-vivid-3.19.0/include/drm/ttm/ttm_bo_driver.h:855 qxl_surface_id_alloc+0x306/0x390 [qxl]() Sep 9 23:25:55 desktop kernel: [ 2700.313925] Modules linked in: ufs qnx4 hfsplus hfs minix ntfs msdos jfs xfs libcrc32c cpuid joydev rfcomm bnep bluetooth snd_hda_codec_generic snd_hda_intel snd_hda_controller snd_hda_codec snd_hwdep snd_pcm snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq kvm_intel snd_seq_device kvm snd_timer serio_raw snd qxl ttm drm_kms_helper drm soundcore i2c_piix4 8250_fintek mac_hid parport_pc ppdev lp parport btrfs xor raid6_pq psmouse sym53c8xx scsi_transport_spi floppy pata_acpi Sep 9 23:25:55 desktop kernel: [ 2700.317404] CPU: 0 PID: 1200 Comm: Xorg Not tainted 3.19.0-26-generic #28~14.04.1-Ubuntu Sep 9 23:25:55 desktop kernel: [ 2700.330373] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Bochs 01/01/2011 Sep 9 23:25:55 desktop kernel: [ 2700.330381] ffffffffc02c7660 ffff88006a5afb98 ffffffff817aeed7 0000000000000000 Sep 9 23:25:55 desktop kernel: [ 2700.330401] 0000000000000000 ffff88006a5afbd8 ffffffff81074d8a ffff88006051ade0 Sep 9 23:25:55 desktop kernel: [ 2700.330417] ffff880004793400 0000000000000402 ffff880004793458 ffff88007b12e000 Sep 9 23:25:55 desktop kernel: [ 2700.330422] Call Trace: Sep 9 23:25:55 desktop kernel: [ 2700.334321] [<ffffffff817aeed7>] dump_stack+0x45/0x57 Sep 9 23:25:55 desktop kernel: [ 2700.364142] [<ffffffff81074d8a>] warn_slowpath_common+0x8a/0xc0 Sep 9 23:25:55 desktop kernel: [ 2700.364165] [<ffffffff81074e7a>] warn_slowpath_null+0x1a/0x20 Sep 9 23:25:55 desktop kernel: [ 2700.364178] [<ffffffffc02c2026>] qxl_surface_id_alloc+0x306/0x390 [qxl] Sep 9 23:25:55 desktop kernel: [ 2700.364184] [<ffffffffc02c0732>] qxl_bo_check_id+0x32/0x50 [qxl] Sep 9 23:25:55 desktop kernel: [ 2700.364190] [<ffffffffc02c4afb>] qxl_release_reserve_list+0xeb/0x110 [qxl] Sep 9 23:25:55 desktop kernel: [ 2700.364195] [<ffffffffc02c40ab>] qxl_process_single_command+0x48b/0x7f0 [qxl] Sep 9 23:25:55 desktop kernel: [ 2700.364200] [<ffffffffc02c444f>] qxl_execbuffer_ioctl+0x3f/0x90 [qxl] Sep 9 23:25:55 desktop kernel: [ 2700.364265] [<ffffffffc01fba4c>] drm_ioctl+0x1ec/0x660 [drm] Sep 9 23:25:55 desktop kernel: [ 2700.368147] [<ffffffff811ac885>] ? do_mmap_pgoff+0x2f5/0x3c0 Sep 9 23:25:55 desktop kernel: [ 2700.376225] [<ffffffff811ffbf8>] do_vfs_ioctl+0x2f8/0x510 Sep 9 23:25:55 desktop kernel: [ 2700.377236] [<ffffffff81062335>] ? trace_do_page_fault+0x45/0x100 Sep 9 23:25:55 desktop kernel: [ 2700.377241] [<ffffffff811ffe91>] SyS_ioctl+0x81/0xa0 Sep 9 23:25:55 desktop kernel: [ 2700.377945] [<ffffffff817b688d>] system_call_fastpath+0x16/0x1b Sep 9 23:25:55 desktop kernel: [ 2700.377949] ---[ end trace 162123e0358b110a ]--- Sep 9 23:26:00 desktop kernel: [ 2704.398492] ------------[ cut here ]------------ I'm not sure wich component crashes but it seems it is QXL or QEMU, or may be the issue is in libvirt (?)
