Bug ID: 103211
Summary: Unable to power off on MacbookPro11,4
Product: ACPI
Version: 2.5
Kernel Version: 4.2.0-rc7
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Hi,
I've been trying to get the new MacbookPro11,4 to be able to power down all day
with no luck. When shutting down it gets to
reboot: power down
And hangs. There are no logs at this point as it is already running in the
systemd initrd image by this point. I've tried with reboot=pci (which seems to
work for many previous macbooks) and reboot=acpi (which works on other older
macbooks) and neither of these have worked. I'm currently running on the latest
commit (as of 2 hours ago) to 4.2.0-rc7 and this issue remains. It also occurs
in 4.1.5, so I do not believe it to be a regression.
It does the same thing when going to sleep, or hibernating. In the case of
hibernation if I hold in the power button until it powers off, then turn it
back on it will resume cleanly. The screen turns off for sleep (unlike
hibernate/shutdown) but it does not shut down; the fans stay running and it is
impossible to wake it back up without forcing it to power off and back on.
Let me know if there is any more info/logs/photo of the part where it hangs
required, or if this should be two bugs, one for Power-Off and the other for
Power-Sleep-Wake.
