Irq/9-acpi process using 27% cpu

Support Kernel
1

I see this process constantly using 20+% cpu

PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
129 root     -51   0       0      0      0 S  27.2   0.0      9,04 [irq/9-acpi]

What is this process? And can I config something not to use as much so often?
I’m using Manjaro cu Gnome

Linux radu-gram 6.9.0-1-MANJARO #1 SMP PREEMPT_DYNAMIC Mon May 13 07:01:28 UTC 2024 x86_64 GNU/Linux

How long has this been this issue happening to you? Have you tried with another kernel like 6.6 LTS?

I was in the last day, Strangely it doesn’t show anymore, phew…

But now this process is using cpu almost all the time

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
 869812 gnome     20   0 5528576 357712 123348 S  23.9   1.1   0:32.54 /usr/bin/gnome-shell

irq/9-acpi appeared again using cpu, an I see this

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
    129 root     -51   0       0      0      0 R  29.0   0.0 125:45.31 irq/9-acpi
