I have a lot of spurious interrupts on my Pine64.
Even in idle single user mode:
# pstree
-+= 00001 root /sbin/init --
\-+= 01783 root -sh (sh)
\-+= 01804 root pstree
\--- 01805 root ps -axwwo user,pid,ppid,pgid,command

When building world (3 threads) the frequency is about a few each second,
idle perhaps a few each hour.
I have ethernet connected and a small USB hard disk with it's own power
supply, which hosts /usr/{src,obj,ports}.
In addition I noticed an ethernet lock up from time to time. Executing
"dmesg" in a ssh session is often sufficient to trigger it.
The weird thing is that after some boots (perhaps 1 out of 10) the spurious
interrupts do not happen! I have not been able to detect a pattern here.
Can others reproduce these findings?
Thanks in advance for any hints.
