Thanks. How long does the /lib/udev/accelerometer call take for you? (it
should be more or less instantaneous). It seems it takes a lot longer
when it runs during boot, so we need some better debugging there.
Could you re-enable /lib/udev/rules.d/61-accelerometer.rules and change
it to this:
SUBSYSTEM=="input", ACTION!="remove", ENV{ID_INPUT_ACCELEROMETER}=="1",
IMPORT{program}="/usr/bin/strace -fvvtts1024 -o /run/accel.trace
/lib/udev/accelerometer %p"
then reboot, and attach /run/accel.trace here?
