Description Dominic Fandrey freebsd_committer freebsd_triage 2016-05-31 15:18:02 UTC 
My system (the version selection in bugzilla does not offer 10.3-stable):
FreeBSD AprilRyan.norad 10.3-STABLE FreeBSD 10.3-STABLE #0 r300145M: Wed May 18 17:00:58 CEST 2016     root@AprilRyan.norad:/usr/obj/S403/amd64/usr/src/sys/S403  amd64

It's patched for Haswell graphics:
https://reviews.freebsd.org/D5837

When I suspend/resume the following stops working:
- `sysctl hw.acpi.acline` sticks to whatever state it had during resume
- No more sound over HDMI (it works after a fresh boot)
- Acpi events like the suspend key

I can attach an acpi dump if that is useful. It does not change between suspend/resume, though.
