On kernels 6.= 1.44 and 6.1.45, the QEMU VNC window stays dark, not switching to any of the gue= st's video modes and the VM process uses only ~64 MB of RAM of the assigned 2 GB, indefinitely. It's like the VM is paused/halted/stuck before even starting.= The process can be killed successfully and then restarted again (with the same result), so it is not deadlocked in kernel or the like. Kernel 6.1.43 works fine. I have also tried downgrading CPU microcode from 20230808 to 20230719, but = that did not help. The CPU is AMD Ryzen 5900. I suspect some of the newly added mitigations ma= y be the culprit? --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
