Public bug reported:
I have noticed first that I have bad keyboard response. When I leave a
key pressed, I have had pause every few seconds ...
That problem disappeared when I have unloaded acer_wmi module.
But high load, and bad machine response stayed.
For example, when I type this text i firefox, and leave a key pressed I
have about 50% load on both of cpu-s !
When I boot with acpi=off, that high CPU load disappears, but this is
notebook - it is unusable without acpi (poweroff, suspend etc ...)
I have also registered this.
$ dmesg | greo storm
[ 1.029542] ACPI: EC: GPE storm detected, transactions will use
polling mode
Also, I have 1 ERR on interrupts:
