Description Tomasz Kłoczko 2017-04-08 19:01:48 UTC

HW: pine64+
Still to boot fedora kernel must be used uboot with ATF but at lease it boots and I just found that 4.11 rc5 git 3.1 was able correctly load eth0 modules so I have now network.

Comment 1 Peter Robinson 2017-08-06 17:15:10 UTC

This was random and I've not seen it of late but it's a bit of a spurious crash and never happened at the same time/place
