Hi,
Thanks for report. When pasting dmesg output, please do not wrap the
lines because it is difficult to read it.
This looks like known issue:
https://wiki.tizen.org/wiki/Exynos_Mainline_Kernel_TODO/Odroid_XU3_lockdep_warn_during_music_playback
Waiting for someone brave enough to fix it...
But actually more important item is following real lockup, failing
multi_v7 boot ~20% of times:

Hi,
Thanks for report. When pasting dmesg output, please do not wrap the
lines because it is difficult to read it.
This looks like known issue:

Waiting for someone brave enough to fix it...
But actually more important item is following real lockup, failing
