Subject: Dell XPS 13 9370: thermal thermal_zone10: failed to read out thermal
 zone (-61)

Dear Linux folks,


On the Dell XPS 13 9370 with Debian sid/unstable, Linux warns about a 
thermal related issue:

     [    0.000000] Linux version 5.18.0-4-amd64 
(debian-kernel@...ts.debian.org) (gcc-11 (Debian 11.3.0-5) 11.3.0, GNU 
ld (GNU Binutils for Debian) 2.38.90.20220713) #1 SMP PREEMPT_DYNAMIC 
Debian 5.18.16-1 (2022-08-10)
     […]
     [    0.000000] DMI: Dell Inc. XPS 13 9370/0RMYH9, BIOS 1.21.0 
07/06/2022
     […]
     [   15.722394] thermal thermal_zone10: failed to read out thermal 
zone (-61)

Can that warning be addressed?


Kind regards,

Paul


PS: There are twelve thermal zones:
