Reproducible panic in -current amd64 (repeat)

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

While doing 'make test' in pkgsrc/lang/python313, I get consistent
panic every time I try to run it, somewhere around test 288, as
follows:
...
Crash version 10.99.12, image version 10.99.12.
Kernel compiled without options LOCKDEBUG.
System panicked: kernel diagnostic assertion
"it->it_time.it_interval.tv_sec >= 0" failed: file
"/home/sysbuild/src/sys/kern/kern_time.c", line 862

Does anybody else see this? The system is a ProxMox guest running
relatively recent kernel and userland:

$ uname -a
NetBSD ym1r.lorien.lan 10.99.12 NetBSD 10.99.12 (GENERIC) #2: Thu Oct
31 22:28:14 GMT 2024
root%ym1r.lorien.lan@localhost:/bd/sysbuild/amd64/obj/home/sysbuild/src/sys/arch/amd64/compile/GENERIC
amd64

The CPU emulation is the default one gets - x86-64-v2-AES. Previously
I tried runing the same with CPU host, this killed the entire ProxMox
server...

suspect it has fallen into the spam filters black hole).
