Hi,

I recently updated my laptop's BIOS and now my hardware wifi key fails,
it doesn't disable the wifi chip anymore.
In dmesg I found an error message, which indicates a event_id changed. (
dmesg.txt )

I tried to fix the issue by patching hp_wmi.c, to match the new event_id
which seems to be 8, but I couldn't get it working. (
hp_wmi_wireless_event_id_changed.patch ).

I'm willing to test patches and I will try to test if the issues occurs
with the recent rc release of linux.
