after hibernation and comeback

Tree: Mainline
Status: NEW
Severity: normal

Most recent kernel where this bug did not occur:
Distribution:
Hardware Environment: IBM T42
Software Environment: Debian GNU/Linux 4.0 (kernel 2.6.21)
Problem Description:
When the system boots up (freshly), the cpu frequency (governer conservative)
works properly and switches the cpu speed smoothly from low to high and
viceversa based on the application using the system
When the system is suspended to disk, and the system comes back after suspend,
the conservative governer stops working. Occasionally it starts working after a
very long time
