"Disabling IRQ #9" - how to check for impact
Hello Debianists,
some days ago I updated the BIOS of my Lenovo IdeaPad S145-15IIL (had to
boot a certain proprietary OS for this). I think since then there is a
new error in the kernel log. I never noticed it before.
[ 9.967601] irq 9: nobody cared (try booting with the "irqpoll" option)
[ 9.967607] CPU: 1 PID: 981 Comm: sddm-greeter Tainted: G
OE 5.10.0-13-amd64 #1 Debian 5.10.106-1
[ 9.967608] Hardware name: LENOVO 81W8/LNVNB161216, BIOS DKCN54WW
01/27/2022
[ 9.967608] Call Trace:
[ 9.967615] dump_stack+0x6b/0x83
[...]
[ 9.967636] handlers:
[ 9.967639] [<00000000872fa119>] acpi_irq
[ 9.967640] Disabling IRQ #9
This IRQ seems to be related to ACPI on this machine. I am unsure, what
exactly gets diabled and what might be the impact. So far I notice no
problems with performance or overheating, compiling a small tool went as
always I would say.
Do you have any hints for me about what I should/could check?
Regards,
Christian
