LinuxACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296] Error and Solution

I'm getting the following error in /var/log/messages file and my sensors command is also not working:


Aug 13 21:22:24 backup kernel: [ 8.681901] ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296]
Aug 13 21:22:24 backup kernel: [ 8.683378] it87 it87.656: Detected broken BIOS defaults, disabling PWM interface

How do I fix this problem under Debian or Ubuntu Linux desktop system?

You can fix this problem by editing /etc/default/grub file as follows:
# vi /etc/default/grub
Update GRUB_CMDLINE_LINUX as follows:

 
GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
 

Save and close the file. Update /boot/grub/grub.cfg by running the following command:
# update-grub
Reboot the system:
# reboot
