--- Comment #2 from Sean Christopherson (seanjc@google.com) ---
Are you able to bisect to an exact commit?  There are significant KVM changes
in 6.13, but they're almost all related to memory management.  I can't think of
anything that would manifest as an unexpected single step #DB, especially not
with any consistency.

And just to double check, the only difference in the setup is that the host
kernel was upgraded from v6.12 => v6.13?  E.g. there was no QEMU update or
guest-side changes?
