New: Changing the default cpufreq govenor freezes suspend
https://bugzilla.kernel.org/show_bug.cgi?id=19132
Summary: Changing the default cpufreq govenor freezes suspend
Product: Power Management
Version: 2.5
Kernel Version: 2.6.35
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: cpufreq
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Regression: No
Since 2.6.35 my Thinkpad X200 with Intel Chipset freezes (the screen is getting black with just a cursor and hangs forever there) on suspend when the default cpufreq govenor is changed. This happens beacuse pm-utils changes the default govenor when going on suspend(-to-ram, but to-disk also I think).
When I disable that changing of the govenor suspend will work again.
This may have to do something with the Intel Graphic as well, because the problem only occurs when beeing on X. Without X the suspend works fine.
With 2.6.34 everything worked well.
