Hi,
This commit breaks reboot on my performance test machines.
src/sys/dev/acpi/acpi.c
----------------------------
revision 1.373
date: 2019/08/28 22:39:09; author: kettenis; state: Exp; lines: +2 -1;
commitid: QyX9yOMI2XcbppRc;
Use ACPI information to attach PCI busses like we do on arm64. There are a
few additional quirks though, and attaching the PCI busses is delayed to
replicate the existing code more closely. That may be changed in the
future. Also tweak how we handle MSI support and respect to ACPI flag
that says we shouldn't attempt to use MSIs.
Some fallout is expected.

If I understand the assemlby correctly, sc->iot is NULL, so it
panics at sc->iot->read_2.
