--- Comment #30 from Mario Limonciello (AMD) (mario.limonciello@amd.com) ---
Sorry two more things.

First - there are two sets of coefficients (one for AC and for DC).  You can
see in current_power_limits_show() that it will return the table matching your
power mode.

Please capture like this:
1) Start on DC, capture the file.
2) Switch to AC, capture the file.
3) Suspend the machine
4) Unplug adapter
5) Resume
6) Capture the file (while you're on DC)
7) Switch to AC, capture the file.

This will let us confirm whether or not there is a problem with the table.

Second - after the issue has occurred, does changing the acpi platform profile
from sysfs or powerprofilesctl recover it?
