Got an oops with 4.14 that hung firefox (like the ubuntu 4.13 kernel), had to hard-reset because the restart process couldn't kill my session.
The 4.14-rc2 mainline kernel has some other bugs: network-manager can't get an ip via dhcp, I have to manually run sudo dhclient (sometimes multiple times) to get an ip, and my syslog is full of these apport errors (I have to kill cups-browsed to stop it): audit: type=1400 audit(1506762106.935:92): apparmor="DENIED" operation="create" profile="/usr/sbin/cups-browsed" pid=891 comm="cups- browsed" family="unix" sock_type="stream" protocol=0 requested_mask="create" denied_mask="create" The log for the oops: [ 963.083894] Oops: 0002 [#1] SMP [ 963.083896] Modules linked in: rfcomm cmac bnep arc4 snd_hda_codec_hdmi snd_usb_audio snd_usbmidi_lib nls_iso8859_1 intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp snd_hda_codec_realtek snd_seq_midi snd_hda_codec_generic snd_seq_midi_event kvm_intel kvm ath10k_pci snd_rawmidi ath10k_core irqbypass snd_hda_intel ath crct10dif_pclmul snd_hda_codec crc32_pclmul mac80211 snd_hda_core ghash_clmulni_intel wil6210 snd_seq pcbc btusb snd_hwdep btrtl snd_pcm btbcm aesni_intel snd_seq_device cfg80211 btintel snd_timer aes_x86_64 bluetooth crypto_simd snd glue_helper eeepc_wmi joydev cryptd mei_me asus_wmi intel_rapl_perf sparse_keymap wmi_bmof input_leds ecdh_generic soundcore ioatdma shpchp mei mac_hid parport_pc ppdev lp parport ip_tables x_tables autofs4 hid_logitech_hidpp hid_logitech_dj hid_generic [ 963.083931] usbhid hid nouveau mxm_wmi video ttm drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops drm igb e1000e nvme dca nvme_core ptp pps_core i2c_algo_bit ahci libahci wmi [ 963.083943] CPU: 13 PID: 17792 Comm: firefox Not tainted 4.14.0-041400rc2-generic #201709242031 [ 963.083945] Hardware name: System manufacturer System Product Name/PRIME X299-DELUXE, BIOS 0702 08/08/2017 [ 963.083948] task: ffff9b6f568a8000 task.stack: ffffb453ce1c4000 [ 963.083951] RIP: 0010:security_vm_enough_memory_mm+0x38/0x60 [ 963.083953] RSP: 0018:ffffb453ce1c7d98 EFLAGS: 00010283 [ 963.083957] RAX: 0000000000000800 RBX: ffffffffbe58c0e8 RCX: 0000000008000070 [ 963.083959] RDX: ffff9b6f12b66e10 RSI: 0000000000000800 RDI: ffff9b6f4aae7000 [ 963.083961] RBP: ffffb453ce1c7db0 R08: ffffffffbda04580 R09: ffff9b6f546fe440 [ 963.083966] R10: ffff9b6f9ffd4000 R11: 0000000000000000 R12: ffff9b6f4aae7000 [ 963.083968] R13: 0000000000000800 R14: 0000000000000800 R15: 0000000000000000 [ 963.083971] FS: 00007f5113a26740(0000) GS:ffff9b6f5eb40000(0000) knlGS:0000000000000000 [ 963.083974] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 963.083975] CR2: 00000000000007e0 CR3: 000000100b965001 CR4: 00000000003606e0 [ 963.083978] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 963.083980] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 963.083982] Call Trace: [ 963.083986] copy_process.part.34+0xbad/0x1aa0 [ 963.083989] _do_fork+0xcf/0x3a0 [ 963.083992] ? get_unused_fd_flags+0x30/0x40 [ 963.083994] SyS_clone+0x19/0x20 [ 963.083997] do_syscall_64+0x61/0x120 [ 963.084001] entry_SYSCALL64_slow_path+0x25/0x25 [ 963.084003] RIP: 0033:0x7f510489f250 [ 963.084005] RSP: 002b:00007ffcdffa5250 EFLAGS: 00000202 ORIG_RAX: 0000000000000038 [ 963.084007] RAX: ffffffffffffffda RBX: 00007f5112719000 RCX: 00007f510489f250 [ 963.084009] RDX: 0000000000000000 RSI: 00007f511271ce80 RDI: 0000000000800600 [ 963.084012] RBP: 00007ffcdffa5330 R08: 0000000000000000 R09: 0000000000000000 [ 963.084014] R10: 0000000000000000 R11: 0000000000000202 R12: 00007f51125a08a0 [ 963.084016] R13: 00007f51048a8410 R14: 00007ffcdffa5290 R15: 00007f51068705e0 [ 963.084018] Code: 53 48 8b 1d eb 93 9d 00 49 89 fc 49 89 f5 48 81 fb f0 c1 58 be 75 0e eb 1d 48 8b 1b 48 81 fb f0 c1 58 be 74 11 4c 89 ee 4c 89 e7 <ff> 53 18 85 c0 7f e7 31 d2 eb 05 ba 01 00 00 00 4c 89 ee 4c 89 [ 963.084035] RIP: security_vm_enough_memory_mm+0x38/0x60 RSP: ffffb453ce1c7d98 [ 963.084036] CR2: 00000000000007e0 [ 963.084613] ---[ end trace de026f54edcaf242 ]--- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720263 Title: BUG: unable to handle kernel paging request at ffffffffffffffe1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
