Thanks Takashi.
I've installed your dell_laptop-kmp-default build, and updated the Dell
keyboard hwdb. The "dell_wmi: Unknown key 153 pressed" messages are no longer
seen, but the workqueue WARNINGs are still encountered on rfkill, resulting in
system lock-up:
[ 35.094885] atkbd serio0: Unknown key pressed (translated set 2, code 0x88
on isa0060/serio0).
[ 35.094888] atkbd serio0: Use 'setkeycodes e008 <keycode>' to make it known.
