I just noticed that my dmesg had been flooded with backtraces, appearing to be of KVM origin. I realize that my kernel is tainted, and slightly outdated, however, i just wanted to drop the log here in case it might be useful, but feel free to completely ignore it :) i am not subscribed to the kvm list, so please cc me in case you need further info.. my entire dmesg was flooded with backtraces looking practically identical to this one, so i will only paste a few of them, however, should you want more(though from a quick look they appear identical), i can put online the complete log kvm_handle_exit: unexpected, valid vectoring info and exit reason is 0x9 ------------[ cut here ]------------ WARNING: at arch/x86/kvm/x86.c:185 kvm_queue_exception_e+0x63/0x70 [kvm]() Modules linked in: tun ext3 jbd mbcache usb_storage cryptomgr cbc aes_x86_64 aes_generic dm_crypt dm_mod crypto_blkcipher sha256_generic crypto_algapi coretemp it87 hwmon_vid hwmon snd_seq kvm_intel kvm fuse nvidia(P) snd_usb_audio snd_hda_intel snd_usb_lib snd_rawmidi snd_seq_device snd_pcm snd_timer snd_hwdep psmouse thermal ehci_hcd rtc snd ohci1394 ieee1394 soundcore i2c_core processor snd_page_alloc r8169 button Pid: 20168, comm: kvm Tainted: P W 2.6.27.3 #1 Call Trace: [] warn_on_slowpath+0x64/0xb0 [] paging64_gva_to_gpa+0x21/0x50 [kvm] [] gfn_to_hva+0x9/0x70 [kvm] [] kvm_read_guest_page+0x61/0x70 [kvm] [] kvm_read_guest+0x48/0x80 [kvm] [] load_guest_segment_descriptor+0x6e/0xb0 [kvm] [] kvm_queue_exception_e+0x63/0x70 [kvm] [] kvm_task_switch+0x2ee/0x9f0 [kvm] [] ioapic_service+0x1ec/0x340 [kvm] [] __down_read+0x17/0xa6 [] kvm_arch_vcpu_ioctl_run+0x266/0x6f0 [kvm] [] kvm_vcpu_ioctl+0x2b2/0x480 [kvm] [] try_to_wake_up+0xf6/0x1b0 [] __wake_up_common+0x5a/0x90 [] __wake_up+0x43/0x70 [] wake_futex+0x1f/0x30 [] do_futex+0x881/0xa70 [] handle_io+0x0/0x60 [kvm_intel] [] vfs_ioctl+0x36/0xb0 [] vfs_ioctl+0x2f/0xb0 [] do_vfs_ioctl+0x28b/0x2f0 [] sys_ioctl+0xa1/0xb0 [] system_call_fastpath+0x16/0x1b ---[ end trace dc61957677c4cb77 ]--- kvm_handle_exit: unexpected, valid vectoring info and exit reason is 0x9 ------------[ cut here ]------------ WARNING: at arch/x86/kvm/x86.c:185 kvm_queue_exception_e+0x63/0x70 [kvm]() Modules linked in: tun ext3 jbd mbcache usb_storage cryptomgr cbc aes_x86_64 aes_generic dm_crypt dm_mod crypto_blkcipher sha256_generic crypto_algapi coretemp it87 hwmon_vid hwmon snd_seq kvm_intel kvm fuse nvidia(P) snd_usb_audio snd_hda_intel snd_usb_lib snd_rawmidi snd_seq_device snd_pcm snd_timer snd_hwdep psmouse thermal ehci_hcd rtc snd ohci1394 ieee1394 soundcore i2c_core processor snd_page_alloc r8169 button Pid: 20168, comm: kvm Tainted: P W 2.6.27.3 #1 Call Trace: [] warn_on_slowpath+0x64/0xb0 [] paging64_gva_to_gpa+0x21/0x50 [kvm] [] gfn_to_hva+0x9/0x70 [kvm] [] kvm_read_guest_page+0x61/0x70 [kvm] [] kvm_read_guest+0x48/0x80 [kvm] [] load_guest_segment_descriptor+0x6e/0xb0 [kvm] [] kvm_queue_exception_e+0x63/0x70 [kvm] [] kvm_task_switch+0x2ee/0x9f0 [kvm] [] ioapic_service+0x1ec/0x340 [kvm] [] __down_read+0x17/0xa6 [] kvm_arch_vcpu_ioctl_run+0x266/0x6f0 [kvm] [] kvm_vcpu_ioctl+0x2b2/0x480 [kvm] [] try_to_wake_up+0xf6/0x1b0 [] __wake_up_common+0x5a/0x90 [] __wake_up+0x43/0x70 [] wake_futex+0x1f/0x30 [] do_futex+0x881/0xa70 [] handle_io+0x0/0x60 [kvm_intel] [] vfs_ioctl+0x36/0xb0 [] vfs_ioctl+0x2f/0xb0 [] do_vfs_ioctl+0x28b/0x2f0 [] sys_ioctl+0xa1/0xb0 [] system_call_fastpath+0x16/0x1b ---[ end trace dc61957677c4cb77 ]--- kvm_handle_exit: unexpected, valid vectoring info and exit reason is 0x9 ------------[ cut here ]------------ WARNING: at arch/x86/kvm/x86.c:185 kvm_queue_exception_e+0x63/0x70 [kvm]() Modules linked in: tun ext3 jbd mbcache usb_storage cryptomgr cbc aes_x86_64 aes_generic dm_crypt dm_mod crypto_blkcipher sha256_generic crypto_algapi coretemp it87 hwmon_vid hwmon snd_seq kvm_intel kvm fuse nvidia(P) snd_usb_audio snd_hda_intel snd_usb_lib snd_rawmidi snd_seq_device snd_pcm snd_timer snd_hwdep psmouse thermal ehci_hcd rtc snd ohci1394 ieee1394 soundcore i2c_core processor snd_page_alloc r8169 button Pid: 20168, comm: kvm Tainted: P W 2.6.27.3 #1 Call Trace: [] warn_on_slowpath+0x64/0xb0 [] paging64_gva_to_gpa+0x21/0x50 [kvm] [] gfn_to_hva+0x9/0x70 [kvm] [] kvm_read_guest_page+0x61/0x70 [kvm] [] kvm_read_guest+0x48/0x80 [kvm] [] load_guest_segment_descriptor+0x6e/0xb0 [kvm] [] kvm_queue_exception_e+0x63/0x70 [kvm] [] kvm_task_switch+0x2ee/0x9f0 [kvm] [] ioapic_service+0x1ec/0x340 [kvm] [] __down_read+0x17/0xa6 [] kvm_arch_vcpu_ioctl_run+0x266/0x6f0 [kvm] [] kvm_vcpu_ioctl+0x2b2/0x480 [kvm] [] try_to_wake_up+0xf6/0x1b0 [] __wake_up_common+0x5a/0x90 [] __wake_up+0x43/0x70 [] wake_futex+0x1f/0x30 [] do_futex+0x881/0xa70 [] handle_io+0x0/0x60 [kvm_intel] [] vfs_ioctl+0x36/0xb0 [] vfs_ioctl+0x2f/0xb0 [] do_vfs_ioctl+0x28b/0x2f0 [] sys_ioctl+0xa1/0xb0 [] system_call_fastpath+0x16/0x1b ---[ end trace dc61957677c4cb77 ]--- mvh.
