Bug#568126: lm-sensors: Resource conflicts policy in kernel has changed



Package: lm-sensors
Severity: normal


This looks like a consequence of a recent change in kernel policy
regarding resource conflicts.  According to the 'kernel-parameters.txt'
file in the kernel documentation, the default value of the parameter
"acpi_enforce_resources" has changed:

$ grep -A 15 acpi_enforce_resources Documentation/kernel-parameters.txt 
	acpi_enforce_resources=	[ACPI]
			{ strict | lax | no }
			Check for resource conflicts between native drivers
			and ACPI OperationRegions (SystemIO and SystemMemory
			only). IO ports and memory declared in ACPI might be
			used by the ACPI subsystem in arbitrary AML code and
			can interfere with legacy drivers.
			strict (default): access to resources claimed by ACPI
			is denied; legacy drivers trying to access reserved
			resources will fail to bind to device using them.
			lax: access to resources claimed by ACPI is allowed;
			legacy drivers trying to access reserved resources
			will bind successfully but a warning message is logged.
			no: ACPI OperationRegions are not marked as reserved,
			no further checks are performed.

I recently resolved a very similar issue myself by adding
"acpi_enforce_resources=lax" to my kernel boot line in GRUB.
