On the laptop TUXEDO Book 1406 since Linux 4.16-rc1, sometimes after resume from ACPI S3, the fan starts spinning really loud. Looking with `top`, one kworker thread(?) uses one CPU fully.
Checking with `$ grep -R . /sys/firmware/acpi/interrupts/`, the interrupts seem to three lines have really high values. (I accidentally overrode my file with the high values in it.)
1. /sys/firmware/acpi/interrupts/gpe66: 19 EN enabled unmasked
2. /sys/firmware/acpi/interrupts/sci: 126
3. /sys/firmware/acpi/interrupts/gpe50: 104 EN enabled unmasked
4. /sys/firmware/acpi/interrupts/gpe_all: 126
Do you know of changes in Linux 4.16-rc1, which could cause this?
JFYI: This issues is tracked in the regression reports for Linux 4.16 (http://bit.ly/lnxregrep416 ) with this id:
Please include this line in the comment section of patches that are supposed to fix the issue. Please also mention the string once in other mailinglist threads or different bug tracking entries if you or someone else start to discuss the issue there. By including that string you make it a whole lot easier to track where an issue gets discussed and how far patches to fix it have made it.

Thx for your help. Ciao, Thorsten
might need to check acpidump table to figure out what gpe50 and 66 are.
@paul, do you still have the machine? if yes, please attach the acpidump.
Bug closed as there is no response from Paul.
please feel free to reopen it if you can provide the information needed.
