[ODROID C2] WARNING: CPU: 1 PID: 0 at kernel/time/hrtimer.c:917 hrtimer_forward

Recommended Posts

Hello,

I using up to date Armbian Stretch with kernel 4.19.41-meson64 #5.85 SMP PREEMPT Wed May 8 12:40:37 CEST 2019 aarch64 GNU/Linux.

 

Today about 2 minutes after system boot I have found this warning in kernel log:

When it happened I had one USB device connected to ODROID - E3372h LTE modem (and it was online).

But system working normally after that.

 

I've never had such warning before (with previous kernel - 4.19.20).

Maybe it has something to do with the last Armbian kernel update?
