There are significant KVM chang= es in 6.13, but they're almost all related to memory management. I can't thin= k of anything that would manifest as an unexpected single step #DB, especially n= ot with any consistency. And just to double check, the only difference in the setup is that the host kernel was upgraded from v6.12 =3D> v6.13? E.g. there was no QEMU update or guest-side changes? --=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.=
