Hi,
I have just noticed that sometimes (not everytime...) after a hibernate/resume
cycle, my machine seems to be stuck in its lowest cpu speed state. It has
worked fine for quite some time (although I have only had hibernate working
since FC5).
Has anyone else seen anything like this ? I include below extracts
from /proc/. I have searched around in the logs but not really found
anything, but then I'm not sure what to look for or where.
I thought it might be a 2.6.17 kernel issue, since I recently updated to
2.6.17-1.2145_FC5, but I see the same thing with 2.6.16-1.2133_FC5
cheers Chris
