Hello
in my daily ATF runs on Xen VMs, I see occasional panics like:
kernel/kqueue/t_proc4 (81/956): 1 test cases

The first occurance seems to be this:
https://largo.lip6.fr/~bouyer/NetBSD-tests/xen/HEAD/amd64-pv/202309261750Z_anita.txt
I see it for PV, PVH and HVM runs, but it's quite rare.
I am the only one seeing this ?
