Title:
High load from process irq/65-i2c-INT3 - kernel module tps6598x
Status in linux package in Ubuntu:
Expired
Bug description:
There seems to be an issue with the kernel module tps6598x which puts
the CPU on a high load:
https://forums.intel.com/s/question/0D50P00004fWnUeSAK/nuc10i3-irq-
problem
As soon as the module is unloaded, cpu load is back to normal.
According to a post in the link above the issue is the following:
"My guess is that the IRQ resource is not correct for the PD
controller causing you to see irq flood.
The problem is that the ACPI device entry (the node) on this platform
has 4 I2CSerialBus resources and 4 IRQ resources. The idea is that the
single ACPI device entry can represent up to 4 USB PD controllers. The
problem is that there is no way to know which IRQ resource belongs to
which I2CSerialBus resource :-(.
Andy, this is one of those multi-instantiate I2C slave devices with
HID INT3515.
The only solution I can think of is that we start maintaining DMI
quirk table in drivers/platform/x86/i2c-multi-instantiate.c where we
supply the correct i2c to irq resource mapping for every platform
that has this device(s)."
