Увы, известная проблема в 3.16.7-ckt25-1, которую почему-то не отловили перед point-release (хотя должны были бы; багрепорты посыпались чуть ли не сразу после попадания в proposed-updates). http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=817874 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=819881 ... Если осталось, временно откатиться на 3.16.7-ckt20-1+deb8u4, или попробовать с linux-image-4.[34].0-0.bpo.1-* из backports. > Спасибо заранее. > > Прилагаю фрагмент журнала: > > Apr 3 12:32:59 localhost kernel: [ 3486.521381] BUG: unable to handle > kernel NULL pointer dereference at 0000000000000008 > Apr 3 12:32:59 localhost kernel: [ 3486.521628] IP: [<ffffffffa0413c3d>] > radeon_fence_ref+0xd/0x50 [radeon] > Apr 3 12:32:59 localhost kernel: [ 3486.521899] PGD 0 > Apr 3 12:32:59 localhost kernel: [ 3486.521963] Oops: 0002 [#1] SMP > Apr 3 12:32:59 localhost kernel: [ 3486.522130] Modules linked in: > pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) > cpufreq_stats cpufreq_powersave cpufreq_userspace cpufreq_conservative > bnep bluetooth 6lowpan_iphc binfmt_misc uinput nfsd auth_rpcgss > oid_registry nfs_acl nfs lockd fscache sunrpc fuse loop parport_pc > ppdev lp parport uvcvideo ums_realtek usb_storage videobuf2_vmalloc > videobuf2_memops videobuf2_core v4l2_common videodev media > snd_hda_codec_hdmi wl(PO) snd_hda_codec_realtek snd_hda_codec_generic > snd_hda_intel acer_wmi snd_hda_controller sparse_keymap snd_hda_codec > kvm_amd snd_hwdep k10temp kvm radeon pcspkr joydev evdev cfg80211 > edac_mce_amd serio_raw snd_pcm edac_core snd_timer ttm drm_kms_helper > drm snd rfkill i2c_algo_bit sp5100_tco soundcore i2c_piix4 i2c_core > shpchp wmi ac video button acpi_cpufreq battery processor ext4 crc16 > mbcache jbd2 hid_generic usbhid hid sd_mod crc_t10dif > crct10dif_generic sg crct10dif_common sr_mod cdrom ata_generic > broadcom ohci_pci psmouse tg3 ptp pps_core pata_atiixp libphy thermal > thermal_sys ahci libahci ehci_pci ohci_hcd ehci_hcd usbcore usb_common > libata scsi_mod > Apr 3 12:32:59 localhost kernel: [ 3486.524515] CPU: 1 PID: 3054 Comm: > Xorg Tainted: P O 3.16.0-4-amd64 #1 Debian 3.16.7-ckt25-1 > Apr 3 12:32:59 localhost kernel: [ 3486.524668] Hardware name: Acer Aspire > 5552/Aspire 5552, BIOS V1.03 08/04/2010 > Apr 3 12:32:59 localhost kernel: [ 3486.524787] task: ffff88006ae65630 ti: > ffff88006b1b8000 task.ti: ffff88006b1b8000 > Apr 3 12:32:59 localhost kernel: [ 3486.524908] RIP: > 0010:[<ffffffffa0413c3d>] [<ffffffffa0413c3d>] > radeon_fence_ref+0xd/0x50 [radeon] > Apr 3 12:32:59 localhost kernel: [ 3486.525073] RSP: 0018:ffff88006b1bbb18 > EFLAGS: 00010292 > Apr 3 12:32:59 localhost kernel: [ 3486.525161] RAX: 0000000000000000 RBX: > ffff88006a3355f8 RCX: ffff88006a334d08 > Apr 3 12:32:59 localhost kernel: [ 3486.525277] RDX: 0000000000000001 RSI: > 0000000000000000 RDI: 0000000000000000 > Apr 3 12:32:59 localhost kernel: [ 3486.525392] RBP: ffff88006a335550 R08: > ffff88006a334000 R09: 0000000000000000 > Apr 3 12:32:59 localhost kernel: [ 3486.525507] R10: 0000000000000002 R11: > ffff88006b1bbe08 R12: 0000000000000020 > Apr 3 12:32:59 localhost kernel: [ 3486.525623] R13: ffff88006b1bbbe0 R14: > ffff88006b1bbbb0 R15: ffff88006a3355f8 > Apr 3 12:32:59 localhost kernel: [ 3486.525740] FS: > 00007fc1e16c0980(0000) GS:ffff88006f880000(0000) > knlGS:0000000000000000 > Apr 3 12:32:59 localhost kernel: [ 3486.525872] CS: 0010 DS: 0000 ES: 0000 > CR0: 0000000080050033 > Apr 3 12:32:59 localhost kernel: [ 3486.525971] CR2: 0000000000000008 CR3: > 000000006bbf7000 CR4: 00000000000007e0 > Apr 3 12:32:59 localhost kernel: [ 3486.526088] Stack: > Apr 3 12:32:59 localhost kernel: [ 3486.526123] ffffffffa04740bc > 0020000000096960 0000f04000000100 ffff88006b1bbcd0 > Apr 3 12:32:59 localhost kernel: [ 3486.526260] ffff88006a334000 > ffff88006ae65630 ffff88006ae65630 0000000000000001 > Apr 3 12:32:59 localhost kernel: [ 3486.526396] 0000000000000000 > 0000000000000000 0000000000000000 0000000000000000 > Apr 3 12:32:59 localhost kernel: [ 3486.526532] Call Trace: > Apr 3 12:32:59 localhost kernel: [ 3486.526592] [<ffffffffa04740bc>] ?
