Hi all,
I have one HP test host that failed to boot starting from 4.12-rc1, it
failed to bring up lvm device then dropped me to emergency shell.
...
[ OK ] Started LVM2 PV scan on device 8:1.
[ TIME ] Timed out waiting for device dev-mapper-systemvg\x2dhome.device.
[DEPEND] Dependency failed for /root/workspace.
[DEPEND] Dependency failed for Local File Systems.
[DEPEND] Dependency failed for Mark the need to relabel after reboot.
[DEPEND] Dependency failed for Relabel all filesystems, if necessary.
[ TIME ] Timed out waiting for device dev-di...\x2d918a\x2d091a53637acd.device.
[DEPEND] Dependency failed for /boot.

Welcome to emergGive root password for maintenance
(or type Control-D to continue):
I attached full boot log.
I bisected this issue to this commit, and I've confirmed that host
booted successfully if I revert this commit on top of 4.12-rc3 kernel
(stock 4.12-rc3 kernel failed to boot too).

ACPICA: Disassembler: Enhance resource descriptor detection
ACPICA commit ba5020b2dbe1538e4ccd7ac2dfd8843a690c007f
This change enhances the detection of resource descriptors
within a buffer object. For the end_tag opcode, the second byte
is defined to be either a checksum or zero. All known ASL compilers
insert a zero for this byte. The disassembler now ensures this
byte is zero before deciding that a buffer should be disassembled
to a resource descriptor. This helps eliminate incorrect decisions
when attempting to disassemble a buffer to a resource descriptor.

I'm not familiar with ACPI, I'm not sure what information I should
provide, so please let me know if you need more info to debug.
Thanks,
