Linux users of Sony Z1 series

[Rainer Jochem <>]

Hello,

cpufreqd?

BTW: talking of CPU frequencies: What is the lowest cpu speed you can
get out of your Z1 with Linux? I don't get it below 600MHz (which is 
according to the docs in the speedstep-centrino kernel-driver where a
Intel Datasheet is referenced the official lower limit for the
processor if I've read it correctly) But when running WinXP on the
laptop and having there the speedstepping activated and look at the
System properties, Windows tells me that the processor is running at
something about 280MHz... duh?!?... Perhaps the MHz counter is buggy
which I doubt -- also because Windows tells me a remaining battery
runtime of 5-6h (which is then really possible). 

Perhaps there are some other things involved to throttle the CPU even
slower than the 600MHz. If anyone has similar experience or know where
to look for...

It really removes the USB device, see the following dmesg output:

usb 3-2: new full speed USB device using address 3
Bluetooth: Core ver 2.5
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: HCI USB driver ver 2.6
usbcore: registered new driver hci_usb
--- this happened switching the wireless button to on

usb 3-2: USB disconnect, address 3
--- spicctrl -l 0

usb 3-2: new full speed USB device using address 4
--- spicctrl -l 1

IIRC I've already connected a FW HDD... but I can test it again
tomorrow. (But FW shouldn't cause any trouble)



Cheers,
