Keeping 3.16.0-34 still works. Blackscreen is illuminated. I do not see any splash screen, nor X. Failsafe mode works, booting with "nomodeset" works (but it's slow). When this happens, on the next reboot I do see some "BUG:" lines in syslog, like: Apr 27 21:01:54 portable-alex kernel: [ 2.457904] BUG: unable to handle kernel NULL pointer dereference at (null) Apr 27 21:01:54 portable-alex kernel: [ 2.457911] IP: [< (null)>] (null) Apr 27 21:01:54 portable-alex kernel: [ 2.457913] PGD 51b93d067 PUD 51b8ec067 PMD 0 Apr 27 21:01:54 portable-alex kernel: [ 2.457916] Oops: 0010 [#1] SMP Apr 27 21:01:54 portable-alex kernel: [ 2.457918] Modules linked in: rtsx_pci_sdmmc i915(+) e1000e ahci ptp i2c_algo_bit drm_kms_helper libahci pps_core psmouse drm rtsx_pci wmi video Apr 27 21:01:54 portable-alex kernel: [ 2.457926] CPU: 0 PID: 128 Comm: systemd-udevd Not tainted 3.16.0-36-generic #48-Ubuntu Apr 27 21:01:54 portable-alex kernel: [ 2.457929] Hardware name: LENOVO 20BXCTO1WW/20BXCTO1WW, BIOS JBET45WW (1.10 ) 02/03/2015 Apr 27 21:01:54 portable-alex kernel: [ 2.457930] task: ffff88051be6bd20 ti: ffff88051b9a8000 task.ti: ffff88051b9a8000 Apr 27 21:01:54 portable-alex kernel: [ 2.457932] RIP: 0010:[<0000000000000000>] [< (null)>] (null) Apr 27 21:01:54 portable-alex kernel: [ 2.457934] RSP: 0018:ffff88051b9ab890 EFLAGS: 00010286 Apr 27 21:01:54 portable-alex kernel: [ 2.457936] RAX: 0000000000000246 RBX: ffff88051bbb1928 RCX: 0000000000000001 Apr 27 21:01:54 portable-alex kernel: [ 2.457937] RDX: 0000000000000001 RSI: 00000000ffffeffe RDI: ffff88051bbb1928 Apr 27 21:01:54 portable-alex kernel: [ 2.457938] RBP: ffff88051b9ab8b0 R08: ffff88051bbb0000 R09: 0000000000000246 Apr 27 21:01:54 portable-alex kernel: [ 2.457940] R10: ffff880529403900 R11: ffffffff811a6ddf R12: 00000000ffffeffe Apr 27 21:01:54 portable-alex kernel: [ 2.457941] R13: ffff88051bbb0000 R14: 00000000ffffeffe R15: ffff88051bf90800 Apr 27 21:01:54 portable-alex kernel: [ 2.457942] FS: 00007f8127b4f880(0000) GS:ffff88053dc00000(0000) knlGS:0000000000000000 Apr 27 21:01:54 portable-alex kernel: [ 2.457944] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Apr 27 21:01:54 portable-alex kernel: [ 2.457945] CR2: 0000000000000000 CR3: 000000051b942000 CR4: 00000000003407f0 Apr 27 21:01:54 portable-alex kernel: [ 2.457947] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Apr 27 21:01:54 portable-alex kernel: [ 2.457948] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Apr 27 21:01:54 portable-alex kernel: [ 2.457949] Stack: Apr 27 21:01:54 portable-alex kernel: [ 2.457950] ffffffffc02499fd ffff88051bbb1928 ffff88051bbb7148 ffff88051bbb7148 Apr 27 21:01:54 portable-alex kernel: [ 2.457953] ffff88051b9ab8e8 ffffffffc022e5b7 00000000ffffefff 00000000ffffeffe Apr 27 21:01:54 portable-alex kernel: [ 2.457955] ffff88051bbb0000 ffff88051bbb0000 ffff88051bbb0000 ffff88051b9ab910 Apr 27 21:01:54 portable-alex kernel: [ 2.457957] Call Trace: Apr 27 21:01:54 portable-alex kernel: [ 2.457977] [<ffffffffc02499fd>] ?
