I‘m trying to run a command called sensors-detect and I was recommended to use it87.ko Linux kernel driver. But, when I do modprobe it87, I get the following error under Debian Linux
FATAL: Error inserting it87 (/lib/modules/2.6.32-5-686/kernel/drivers/hwmon/it87.ko): Device or resource busy
How do I fix this problem under Debian GNU/Linux 6.x?
To fix this problem and to load it87 driver, edit /etc/default/grub file, enter:
# vi /etc/default/grub
Update GRUB_CMDLINE_LINUX as follows (keep existing config if any and append acpi_enforce_resources=lax at the end of GRUB_CMDLINE_LINUX)
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
After reboot verify that it87 was loaded, enter:
# lsmod | grep --color it87
Sample outputs:
it87 11487 0 hwmon_vid 1528 1 it87
Finally, run sensors command to get sensors information:
$ sensors
Sample outputs:
