Hi !
I have problem with UHCI usb host in kernel 2.4 and 2.6-testx too.
When I load UHCI module, then CPU in idle state newer use C3 powersave
state. Problem is probably with busmaster acitivity. Busmaster resources
are newer released and in idle mode is used only C1 and C2 state. (see.
drivers/acpi/processor.c). C3 state can be used only if busmaster activity
was not 4x used in last tests in C2 state.
"cat /proc/acpi/processor/CPU0/power" display: busmaster: ffffffff
Is it feature of USB on my Dell D600 notebook, or bug in uhci-hcd in
2.6 and in uhci.c from 2.4 kernel?
module ehci-hcd work fine.
thanks for advice
poli
