Title:
GPE interrupt on Macbook Pro - kworker with high CPU usage
Status in linux package in Ubuntu:
Confirmed
Bug description:
Greetings,
This issue is fixed by booting with the following kernel argument:
acpi_mask_gpe=0x06
The effects of this bug were pretty devastating on the system; very
slow and the fans were spinning very hard. Cores 0 and 1 were running
at nearly 100% on an otherwise idle system.
It seems that this bug is well documented:
https://bugzilla.kernel.org/show_bug.cgi?id=117481 (2016)
https://bugzilla.redhat.com/show_bug.cgi?id=1192856 (2015)
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577629 (2016)
I am new, so I am unsure whether it would be within the scope of
Ubuntu to make it an option during installation to include device-
specific kernel quirks for bugs such as this, and I wanted to check
and see what the go is. If we know it is affecting a certain set of
Macbook Pro's then would it be possible to detect the system and then
add the kernel argument?
Best,
Nick
