Public bug reported:
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.
** Affects: linux-signed (Ubuntu)
Importance: Undecided
Status: New
** Package changed: linphone (Ubuntu) => linux-signed (Ubuntu)
