Ubuntu Zesty Zapus ### gcc-6 with CONFIG_PCI_QUIRKS=y CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS=y After grub, screen turns off. No pre modeset messages. Then system reboot itself. When CONFIG_PCI_QUIRKS not set CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS not set System would boot up to: "Clocksource: Switched to clocksource hpet". then loop ''' Could not create tracefs '' directory Could not create directory for event ''' ### gcc-4.9 system would panic with above settings on. With them off, setting would boot to login prompt. Only one working terminal. Login works. dmesg works lsmod hangs [ 8.436647] BUG: unable to handle kernel paging request at 0000000016000000 [ 8.437448] IP: [] strcmp+0x16/0x30 [ 8.438224] PGD 0 [ 8.438992] Oops: 0000 [#1] SMP [ 8.439750] Modules linked in: [ 8.440506] CPU: 6 PID: 430 Comm: systemd-udevd Not tainted 4.9.0-rc6+ #14 [ 8.441266] Hardware name: Notebook P15SM-A/SM1-A /P15SM-A/SM1-A , BIOS 4.6.5 04/20/2015 [ 8.442239] task: ffffa3d3a436e3c0 task.stack: ffffba3641604000 [ 8.443033] RIP: 0010:[] [] strcmp+0x16/0x30 [ 8.443828] RSP: 0018:ffffba3641607bf0 EFLAGS: 00010202 [ 8.444603] RAX: 000000000000006d RBX: ffffffff97fc33c0 RCX: 0000000000000a1f [ 8.445382] RDX: 000000000000143e RSI: 0000000016000001 RDI: ffffba3641669fe7 [ 8.446149] RBP: ffffba3641607bf0 R08: ffffffff9716cb90 R09: ffffffffc0409000 [ 8.446917] R10: 00003fffffe00000 R11: 0000000000002000 R12: 0000000000000a1f [ 8.447683] R13: 0000000000000010 R14: 000000000000143e R15: 0000000000000000 [ 8.448446] FS: 00007f4830a4c8c0(0000) GS:ffffa3d3afb80000(0000) knlGS:0000000000000000 [ 8.449202] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 8.449957] CR2: 0000000016000000 CR3: 0000000224a12000 CR4: 00000000001406e0 [ 8.450710] Stack: [ 8.451457] ffffba3641607c00 ffffffff9716cba2 ffffba3641607c50 ffffffff974ebede [ 8.452232] ffffffff9716cb90 ffffffff97fb91d0 ffffba3641669fe6 ffffba3641607cb8 [ 8.453005] 0000000000000000 ffffffff97c2e840 ffffba3641687f00 ffffba3641607e80 [ 8.453779] Call Trace: [ 8.454608] [] cmp_name+0x12/0x20 [ 8.455621] [] bsearch+0x5e/0x90 [ 8.456656] [] ?
