[Bug 102301] Shutting down a Windowvs 10 virtual machine (with VGA passthrough) causes a hard crash, every time
https://bugzilla.kernel.org/show_bug.cgi?id=102301 --- Comment #5 from Michael Long --- I'm also affected by this problem but haven't found a pattern to reproduce the problem yet. My observation is, that in former kernel versions, the shutdown problem was on every 10th shutdown but with kernel 4.3 it occurs like every 3rd shutdown, although sometimes I can shutdown and start the Windows 10 VM (still build 10240) several times in a row without issue. Kernel versions: 4.1.x - 4.4-rcX Qemu: 2.4.0, 2.4.1 Pass through devices: VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 980] (rev a1) USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03) I've attached two stack traces, captured by using a serial connection. I would confirm Balázs' observation that the system is not hard locked because the watchdog kicks in over and over until a reset. -- You are receiving this mail because: You are watching the assignee of the bug.-- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

https://bugzilla.kernel.org/show_bug.cgi?id=102301 Balázs László Batári changed: What|Removed |Added CC||b...@bayi.hu --- Comment #2 from Balázs László Batári --- I can - occasionally - reproduce it. Exact same thing: QEMU-KVM with a Windows 10 guest and with GPU passed through. My kernel version is 4.2.4 Qemu: 2.4.0.1 Libvirt: 1.2.20 To reproduce it: - First shutdown is normally fine - Second shutdown triggers it - Reboot is always fine Oh and it is not a "hard freeze", if im on TeamSpeak3 for example the others can still hear me and i can hear them, but keyboard/mouse/screen is not working I couldnt copy out the dmesg, but i made screenshots: https://goo.gl/photos/fqK7Z5gom9FxwVfe9 https://goo.gl/photos/CwtSX4MBktmEP7J57 The strange thing is that we have very similar motherboards with the reporter ( Z87 Pro3 vs Z87 Pro4 ) maybe its something with Asus -- You are receiving this mail because: You are watching the assignee of the bug.-- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
