Quite a few Debian users on QNAP are affected by this "external abort on linefetch" issue. Ian Campell raised this with Andrew Lunn (upstream kernel) last year but Andrew couldn't reproduce it: https://lists.debian.org/debian-arm/2017/07/msg00054.html
RobJE provided additional information but forgot to CC Andrew: https://lists.debian.org/debian-arm/2017/07/msg00059.html Timo Jyrinki is happy to run some tests. He's affected and has a serial console. The bug is still there in the 4.9 kernel we're shipping with Debian kernel. Andrew, what information or access do you need so this can be tracked down? Thank you! -- Martin Michlmayr http://www.cyrius.com/
