I have been experiencing that a kworker thread is hogging CPU for long time:

$ cat /sys/firmware/acpi/interrupts/gpe06
 3058798   enabled

Disabling it solves the problem temporarily:

# echo disable > /sys/firmware/acpi/interrupts/gpe06

There seems to be other people complaining about the same thing:


acpidump attached, dmidecode gives:

/sys/firmware/dmi/tables/DMI: Unexpected end of file
Table is unreachable, sorry.
# dmidecode 3.0
Getting SMBIOS data from sysfs.
SMBIOS 2.4 present.
45 structures occupying 2597 bytes.
Table at 0x7AD14000.

PS: Version of OS X installed is 10.11.

Do you need any more information? I cannot remove NEEDINFO flag.
Comment 8 Gökçen Eraslan 2016-01-11 14:10:29 UTC
I can reproduce it even on android-x86. Is anything else needed?
