Bug ID: 100941
Summary: ACPI: Unable to enable ACPI with Linux 3.14 and higher
on Acer Aspire 5560G
Product: ACPI
Version: 2.5
Kernel Version: 3.13 -> 4.0.7
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Off
Assignee: acpi_power-...@kernel-bugs.osdl.org
Reporter: mrdoctor...@gmail.com
Regression: No
Hello,
I'm experiencing several problems with Linux 3.13 and 3.14. I think those are
coming from the same source, so I'll report all here.
First, for 3.13:
I'm unable to power-off my laptop using the shutdown (shutdown -h -P now,
shutdown -P now) command. The last message I see on the screen is “Will now
halt”. This time the internal HDD stops, but the power is still on.
After reboot, the laptop hangs on initializing initrd.
For 3.14:
When it boots up, the kernel reports “ACPI: Unable to enable ACPI”.
When boot is complete, soundcard & hotplug are not seem to work. If I press the
ACPI power-off button, laptop will shutdown immediately, just like it was
disconnected from the power adaptor. Shutdown command does not power-off the
laptop here too, but the last message on the screen is “System halted”,
although it reboots normally.
I've tested Ubuntu (with the mainline kernel, version 3.14) and also tried it
on Fedora (kernel 4.0.4), Arch (kernel 4.0.7), openSUSE (kernel 3.16) and all
of them have the same problem.
