Public bug reported: Description: Hardware configurations:
CPU: AMD Ryzen 7 5700G with Radeon Graphics Motherboard: Gigabyte B550M D3H OS: Linux Mint 20.3 / with a number of Ubuntu kernels from 5.11, 5.13, and 5.15 Due to the CPU and motherboard, have to use non-packaged kernels for both graphics and network interface to work. Once the CPU virtualization is turned-on, system starts to crash randomly. For Gigabyte motherboard CPU virtualization is called SVM mode. All crashes occurred under CPU SVM mode is enabled. Crashes leave little information to pinpoint the exact process that caused the problem. After almost three months of bad experiences, tried to upgrade kernel from 5.11 to 5.15, none of them helped. The packaged kernel 5.4 doesn't have proper drivers for both the graphics and network interfaces. Methods of replicating the crashes: 1. Turn on the SVM mode in BIOS. 2. Execute glmark2 to benchmark the graphic card performance. 3. System crashes before the benchmark test is done. The syslogs doesn't show any meaningful info for the crashes. https://drive.google.com/drive/folders/1cYbQPdfPSC_6A879xBWRs1jIY7R5ylMU?usp=sharing has all of the info gathered in the painful experiences. Once the SVM mode on the motherboard is turned off (disabled), I no longer experience the same kind of random crashes, and glmark2 can finish without any issues. That's all I can report here. If you need any further information. Please feel free to let me know. Thanks for your attentions. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Summary changed: - Random crashes without any meaningful error logs related to CPU virtualization but a way to replicate the crashes + Random crashes related to CPU virtualization - have a sure way to replicate the crashes ** Description changed: Description: Hardware configurations: CPU: AMD Ryzen 7 5700G with Radeon Graphics Motherboard: Gigabyte B550M D3H OS: Linux Mint 20.3 / with a number of Ubuntu kernels from 5.11, 5.13, and 5.15 Due to the CPU and motherboard, have to use non-packaged kernels for both graphics and network interface to work.
