[ 8.112761] int3403 thermal INT3403:00: Unsupported event [0x91]
[ 10.121722] int3403 thermal INT3403:00: Unsupported event [0x91]
[ 12.165233] int3403 thermal INT3403:00: Unsupported event [0x91]

Is constantly flooding my dmesg. I believe this is also due to missing audio drivers as well. Which is another issue that I am facing.

Realtek ALC1220

Ubuntu 20.04

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

This is not related to audio driver but is related to thermal driver "int3403_thermal.c". It supports upto event 0x90 (See line 21 & line 64 @ https://elixir.bootlin.com/linux/v5.7.1/source/drivers/thermal/intel/int340x_thermal/int3403_thermal.c). Intel may have added a new event that is yet supported in kernel.

It is a good idea to send an email to mailing list "<email address hidden> (open list:THERMAL)" so the driver can be updated accordingly.

Hi,

I tried to send Intel an email but it bounce back.

Your message to <email address hidden> couldn't be delivered.
vger.kernel.org suspects your message is spam and rejected it.

Is it possible for you to get in contact with them?

@junocomp,

These mailing lists don't like HTML-formated emails. You need to send emails in text, and this depends on the email client program you are using.

[Alex Hung (alexhung)]

I sent an email asking about 0x91 to mailing list. I will update here when information is available.

A patch was sent for reviews: https://marc.info/?l=linux-pm&m=159226080621530&w=2

[Juno Computers (junocomp)]

Thank you. Will the patch make it to kernel 5.4?

[Alex Hung (alexhung)]

I also cc'ed stable which includes kernel 5.4. It should be available in kernel 5.4 automatically when (and if) it lands into mainline kernel.

Hi, any updates on this?

It shouldn't be long that Ubuntu 20.04 kernel gets it from upstream.

[Alex Hung (alexhung)]

The fix is included in Ubuntu-5.4.0-43.47 and later

[Juno Computers (junocomp)]

Hi,

The same issue shows up on kernel 5.6 using linux-kernel-oem package.

Ubuntu 20.04

[Juno Computers (junocomp)]

Sorry, meant to say linux-oem-20.04.

[Juno Computers (junocomp)]

Hi, any updates on patching kernel 5.6?

[Adam Richardson (fatman-uk)]

I also have this bug with my new-ish Juno system. I find I'm unable to upgrade my kernel past 5.3.9_1 as the system won't boot - just goes to a blank screen. Could the bugfix be responsible? I see nothing in the logs as the boot doesn't get far enough.
