Title:
Kernel 4.15.0-12 reboots instead of turning off on HP Spectre x360
13-ae004 on battery
Status in linux package in Ubuntu:
Confirmed
Status in linux-signed package in Ubuntu:
New
Bug description:
Ubuntu 18.04, installed from beta 1 ISO + all updates to date
HP Spectre x360 13", model 13-ae004na, secure boot on, latest BIOS
F.15A, Ubuntu is the only system on disk.
When using kernel 4.15.0-12 the system does not power off but instead
reboots. Both halt -p from the command line and menu action leads to
reboot. Booting with previous kernel 4.15.0-10 resolves the issue,
system turns off power as expected.
I am not attaching any logs because I cannot see anything unusual there,
kern.log entries from 4.15.0-10 and 4.15.0-12 seems to be identical (in fact,
there is only one entry there "msr: Direct access to MSR 1b0"). Please let me
know what additional information you may need.
