https://bugzilla.kernel.org/show_bug.cgi?id=219787 Bug ID: 219787 Summary: Guest's applications crash with EXCEPTION_SINGLE_STEP (0x80000004) Product: Virtualization Version: unspecified Hardware: AMD OS: Linux Status: NEW Severity: high Priority: P3 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: rangemachine@xxxxxxxxx Regression: No Created attachment 307665 --> https://bugzilla.kernel.org/attachment.cgi?id=307665&action=edit Debugger attached to Steam.exe Overview ======== Linux 6.13 update introduced problem with Windows guest's applications on AMD processors. Several applications crash with EXCEPTION_SINGLE_STEP (0x80000004). The list of confirmed software: CrystalDiskMark, Visual Studio Code, Steam, Looking Glass server, Windows Tweaker. It never happened prior 6.13 update. I also checked 6.13.3rc and 6.14.1rc updates, problem persists there too. I did quick check differences in KVM/SVM between 6.12 and 6.13 and did not found anything that could set trapflag, so problem could be somewhere deeper inside kernel. Steps to reproduce ================== Run VM with Windows guest, launch any software from the list. Hardware ======== CPU: AMD Ryzen 7 9800X3D (16) @ 5.27 GHz MB: TUF GAMING X870-PLUS WIFI Additional Information ====================== Steam crashes when downloading game, Looking Glass crashes on WinAPI QueryPerformanceCountrer call. Tested on Window 11 22H2/23H2/24H2. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
