Bug#756947: hp-wmi: wifi rfkill can't be reversed

[Alan Wilson <al_wilson@ns.sympatico.ca>]

results of request below:

/sys/class/dmi/id/product_name:HP Compaq nc6230 (PU984AW#ABA)
/sys/class/dmi/id/product_version:F.15
/sys/class/dmi/id/board_name:0944
/sys/class/dmi/id/board_version:KBC Version 40.22


However, I had a repeat of the hangup after a soft kill- even with
hp_wfi removed.

Not sure what to make of that.  Same warnings on shutdown and startup
'waiting to fully populate /dev' resulting in a failed to set power on
IPW_2200 - request timed out - or words to that effect.

Cheers,

Al
