Hi,

it appears that in kernel 2.6.29.2 the behaviour of the rfkill subsystem 
has changed. Under 2.6.29.2 I could trigger a suspend-to-ram, then wake 
up the system, and everything continued smoothly.

Under 2.6.29.2 strange things happen after a wake-up:

* Wlan and bluetooth power, which had been off before suspend, suddenly 
are ON.

* The numbering of the links in /sys/class/rfkill has changed. Formerly 
rfkill1, rfkill2..., now something like rfkill10, rfkill11... The 
numbers increase with every suspend.

This doesn't sound like a big problem and could easily be worked around 
in the suspend-to-ram script. However, the renaming of the links causes 
the wwan connection driver (hso) to crash, and that really sucks. One 
has to repeat the complete, time-consuming initialisation procedure each 
time.

I'm not sure who the culprit is. It could be a kernel bug, or maybe the 
sony-laptop module has to be updated. Could any of the kernel 
specialists please have a look into this?

Thanks in advance,
Bernd
