Package: src:linux Version: 4.2.3-2 Severity: normal Running the Tails test suite[0] (which involves starting virtual machines using KVM) my system is oopsing. The screen locks up when the kernel oopses. The system itself is not locked since I can log in remotely. I can reliably reproduce this problem when booting a KVM virtual machine in UEFI mode. During this portion of the Tails test suite the following will be logged: [22307.737358] BUG: unable to handle kernel paging request at 0000000200000068 [22307.737374] IP: [<ffffffffa07f8e6c>] __mtrr_lookup_var_next+0xc/0xb0 [kvm] [22307.737375] PGD 0 [22307.737377] Oops: 0000 [#3] SMP [22307.737396] Modules linked in: overlay veth vhost_net vhost macvtap macvlan ip6t_REJECT nf_reject_ipv6 ip6table_filter ip6_tables xt_CHECKSUM iptable_mangle ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_nat_ipv4 nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp iptable_filter ip_tables x_tables tun bridge stp llc ctr ccm binfmt_misc cpufreq_userspace cpufreq_stats cpufreq_powersave cpufreq_conservative xfs libcrc32c msr uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core v4l2_common videodev media acpi_call(O) joydev iTCO_wdt iTCO_vendor_support arc4 iwldvm x86_pkg_temp_thermal intel_powerclamp intel_rapl mac80211 iosf_mbi coretemp iwlwifi cfg80211 kvm_intel snd_hda_codec_hdmi thinkpad_acpi nvram evdev psmouse pcspkr serio_raw kvm [22307.737416] rfkill snd_hda_codec_realtek snd_hda_codec_generic tpm_tis tpm snd_hda_intel snd_hda_codec snd_hda_core i915 snd_hwdep drm_kms_helper snd_pcm_oss drm snd_mixer_oss snd_pcm i2c_algo_bit snd_timer snd mei_me lpc_ich wmi i2c_i801 video ac battery soundcore shpchp mei mfd_core processor button fuse autofs4 ext4 crc16 mbcache jbd2 btrfs xor raid6_pq algif_skcipher af_alg dm_crypt dm_mod md_mod sg sd_mod crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel jitterentropy_rng sha256_ssse3 sha256_generic hmac drbg ansi_cprng aesni_intel aes_x86_64 ahci lrw gf128mul glue_helper libahci ablk_helper cryptd sdhci_pci sdhci libata scsi_mod mmc_core e1000e ehci_pci ptp ehci_hcd pps_core xhci_pci xhci_hcd usbcore thermal usb_common thermal_sys [22307.737418] CPU: 3 PID: 11130 Comm: qemu-system-x86 Tainted: G D O 4.2.0-1-amd64 #1 Debian 4.2.1-2 [22307.737419] Hardware name: LENOVO 2349N7G/2349N7G, BIOS G1ET93WW (2.53 ) 03/08/2013 [22307.737420] task: ffff88040a2f0380 ti: ffff880347624000 task.ti: ffff880347624000 [22307.737431] RIP: 0010:[<ffffffffa07f8e6c>] [<ffffffffa07f8e6c>] __mtrr_lookup_var_next+0xc/0xb0 [kvm] [22307.737432] RSP: 0018:ffff880347627ba8 EFLAGS: 00010202 [22307.737432] RAX: 0000000200000058 RBX: 0000000000000000 RCX: 000000000000000c [22307.737433] RDX: ffff8802315b5d48 RSI: ffff8802315b5bf8 RDI: ffff880347627bb8 [22307.737433] RBP: ffff8802315b2a80 R08: 0000000000000002 R09: 0000000000000018 [22307.737434] R10: 00000000000c0000 R11: 00000000ffe20085 R12: 0000000000080000 [22307.737434] R13: 0000000000000000 R14: 0000000000000030 R15: 0000000000000000 [22307.737435] FS: 00007f81ffa84700(0000) GS:ffff88041e2c0000(0000) knlGS:0000000000000000 [22307.737436] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [22307.737436] CR2: 0000000200000068 CR3: 000000032e76e000 CR4: 00000000001426e0 [22307.737437] Stack: [22307.737438] ffffffffa07f978d ffffc90001fd7008 ffff8802315b5bf8 0000000000000000 [22307.737439] 0000000000200000 0000000000000000 0000000200000058 0000000000000000 [22307.737440] 0000000000000c00 ffff8802315b2a80 0000000000000000 ffffffffa07e59d8 [22307.737440] Call Trace: [22307.737450] [<ffffffffa07f978d>] ? kvm_mtrr_check_gfn_range_consistency+0xbd/0x100 [kvm] [22307.737459] [<ffffffffa07e59d8>] ? tdp_page_fault+0x88/0x2a0 [kvm] [22307.737466] [<ffffffffa07caf87>] ? kvm_set_cr0+0xd7/0x1e0 [kvm] [22307.737474] [<ffffffffa07dda93>] ? kvm_mmu_page_fault+0x23/0x110 [kvm] [22307.737477] [<ffffffffa08ca310>] ? vmx_invpcid_supported+0x20/0x20 [kvm_intel] [22307.737480] [<ffffffffa08d4023>] ? vmx_handle_exit+0xc3/0x1300 [kvm_intel] [22307.737486] [<ffffffffa07caa87>] ? kvm_set_shared_msr+0x57/0x90 [kvm] [22307.737488] [<ffffffffa08ca310>] ? vmx_invpcid_supported+0x20/0x20 [kvm_intel] [22307.737496] [<ffffffffa07d9629>] ? kvm_arch_vcpu_ioctl_run+0x339/0x1140 [kvm] [22307.737503] [<ffffffffa07d36cc>] ? kvm_arch_vcpu_load+0x4c/0x1c0 [kvm] [22307.737508] [<ffffffffa07c4154>] ? kvm_vcpu_ioctl+0x2f4/0x570 [kvm] [22307.737511] [<ffffffff8117a7f4>] ? handle_mm_fault+0xec4/0x15d0 [22307.737513] [<ffffffff8107c63a>] ? do_sigtimedwait+0xaa/0x1f0 [22307.737515] [<ffffffff811ca5a3>] ? do_vfs_ioctl+0x2c3/0x4a0 [22307.737517] [<ffffffff81101ffd>] ? __audit_syscall_entry+0xad/0xf0 [22307.737519] [<ffffffff81021d98>] ? syscall_trace_enter_phase1+0xf8/0x150 [22307.737520] [<ffffffff811ca7f6>] ?

I have been able to reproduce this bug with the Debian package I'm filing this bug against as well as self-compiled kernels of 4.2, 4.2.3, and 4.2.4. After many runs and reboots I've managed to hit the oops every single time. After many, many tries, I *cannot* reproduce the oops with a self-compiled 4.1.11 (git revision 205a851). Please let me know if I can provide more information or when there are patches that you'd like me to try.
