https://bugzilla.kernel.org/show_bug.cgi?id=206977 Bug ID: 206977 Summary: AMD gpu Crash after power or reboot the VM Product: Virtualization Version: unspecified Kernel Version: linux-lts 5.4.26 and 5.5.11 and 5.6.rc7 mainline krnel Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: Hans.Wurst424@xxxxxx Regression: No Created attachment 288075 --> https://bugzilla.kernel.org/attachment.cgi?id=288075&action=edit AMD gpu Crash after power or reboot the VM logs Hartdware CPU: AMD RYZEN 1700X MAIBOARD: Asrock X370 Taichi bios: 2.40 last bios version of cpu GPU1: amd radeon r7 260x it works good the rest. GPU2: SAPPHIRE Nitro Plus RX VEGA 64 it works not good the rest with the vfio-pci module. I have a Problem with a corrupt Header on my AMD RX VEGA 64 Card after shutdown the VM. The GPU is with vfio in Qemu VM. arch linux kernel 5.5.10 and linux-lts 5.4. and linxu kernel 5.6rx7 make this BUG on my KVM server. I downgrade the kernel to 5.3.5 an the corrupt Header is fixed and the rest with the vfio-pci module work. I have mesa beta 20.0.1 and archlinux 19.3.4-2 tested. and the BUG is not fixed. see the log lspci -v > lspciv1.log for the 5.3.5 kernel loading in VM after shutdown. see the log lspci -v > lspci_header_corupt.log for the 5.4.26 or 5.5.10 kernel loading in VM after shutdown. see the dmesg >vfio_5.3.5.log for the 5.3.5 kernel loading in VM after shutdown. see the log dmesg > vfio_5.4.26.log for the 5.4.26 or 5.5.10 kernel loading in VM after shutdown. the gpu corrupt header has a gpu then not colling any more and fan rpm of 0. the gpu 30min - 40min after crash is the fan of 100% and pc must remove for engine and waiting 15min gpu coling down. Additional info: * linux linux-lts mesa 19.3.4-2 * config and/or log files etc. * link to upstream bug report, if any Steps to reproduce: I starting a qemu q35 or qemu std VM with the gpu per vfio deice add and shoutdown the vm and the Header is corrupt. I post it in archlinux bug reporter https://bugs.archlinux.org/task/65956 server log after shoutdown VM. lspci -v >lspci_header_corupt.log -- 11:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
