The 'umount /mnt' (da2, an USB stick) at line 1322 happened long before the panic.
If I don't use the external disk (da1) for a while, it stops and starts again when it is
used again. The message at line 1363
(da1:umass-sim1:1:0:0): Polling device for readiness
occured long before the panic. After about a second the disk is ready and works.
It is the kernel from 11-CURRENT snapshot cubox-hummingboard 2016-04-08.
Is there any possibility to get time stamps accompanied with kernel messages on serial
console?
