ACPI interrupts before suspend
Hi,
On my laptop which is ASUS U36SD i'm experiencing high CPU usage after resuming
it form suspend-to-ram state. Actually, seems to be very much the same as
report 29722.
This is pretty much strange issue, because initially this never happened, but
at some point i've started experiencing this issue. That time seemed updating
BIOS helped and everything worked fine for couple of months. But now the issue
is back. Don't know if it's hardware issue or not, no idea how to troubleshot
this.
In the attachments:
- acpidump before and after suspend
- acpi interrupts before and after suspend
- lspci -vvvxxx before and after suspend (where it seems strange nvidia card
and usb3 controller have invalid header type after suspend)
- dmesg since system boot to the moment of after resume
Hope to have some expert opinion and thanks for the help :)
