Freezing of tasks aborted on wp7608 of mangOh_red


Hi All,

After powering on the magOH red with wp7608. In the linux console i get the following error and from then the console is unresponsive

root@swi-mdm9x28:/# [ 59.977961] Freezing of tasks aborted after 0.006 seconds

I had updated the software to latest release 9 . Below is the software version. But still the problem exists

Some one faced this problem ?



Looks like normal behavior to enter sleep mode.

Please try below and see does behavior change:

  1. connect USB cable to PC (driver must be ready)
  2. create wake lock (before it sleep), i.e.

echo test > /sys/power/wake_lock)

  1. enable DevMode
