Hi List! Is there any way to figure out what is causing the CPU to stay in C2?
I currently have this happening for 2 reasons: - uhci_hcd is loaded. I dont think that usb autosuspension is working at all but nobody seems to care. I guess i should install a vanilla kernel so that i can annoy the kernel mailing-list directly. Currently since 2.6.24 from Ubuntu Hardy there is no way for both my cores to go into C3 unless i unload uhci_hcd myself. - sometimes for an totally unknown reason and only after longer uptimes one core is suddenly stuck in C2 as well and i have no idea why. What are your experiences with usb-autosuspension?
