freebsd stable - Sep 2019 - suspend resume broken on 12.1-BETA1?

i've got an amd64 laptop which while running stable had no issues with 
suspend/resume.? after upgrading to beta1 yesterday the system hangs on 
resume.? its a hard hang on resume, can't SSH in and nothing gets into 
the logs.

i've been able to reproduce both with the i915kms module loaded, as well 
as with it *not* loaded.? has anyone else been able to reproduce this?

cheers,
-pete

Could be:

If your hardware is different please include /var/run/dmesg.boot and 
pciconf -lv output as an attachment

It would be handy to know what stable/12 revision you were on before 
(that's *the* open question on that issue)
