udev timeout for mma8450 unless the accelerometer is shaken

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hi,

on my beaglebone-black I get these lines during bootup

[   71.745951] udevd[105]: worker [113]
/devices/ocp.2/4819c000.i2c/i2c-2/2-001d/input/input2/event1 timeout;
kill it
[   71.771991] udevd[105]: seq 1243
'/devices/ocp.2/4819c000.i2c/i2c-2/2-001d/input/input2/event1' killed
[   71.799611] udevd[105]: worker [113] terminated by signal 9 (Killed)

The device is an accelerometer connected via i2c. When I shake it
during bootup I don't get these warnings. Alternative repro:
udevadm trigger --action=add --subsystem-match="input" --subsystem-match="misc"
udevadm settle

The 'udevadm settle' will block until the device is moved. Is that expected?
