Description Jayakrishnan 2005-03-03 22:57:57 UTC

Distribution: gentoo
Kernel      : 2.6.7
Hardware Environment: PC/ I386
Software Environment:
Problem Description:
In the ADM1021 Sensor driver temperature alarm is masked with a constant 0xEC.
For the CHIP ADM1021A, bit 4 is RHIGH, because of the mask the  RHIGH Flag is
cleared in the alarm value. so the Remote Temp High is never reported.

Steps to reproduce:

Good catch. The mask should actually be 0x7c, not 0xec. The bug was present
since the driver was ported (2.5.54).
