Hi all,
Does this dmesg output speaks to anyone here (smp kernel):

Is there anything prior to the "cut here" line?
cheers
# uname -a
Linux G4QS 4.9.0-2-powerpc-smp #1 SMP Debian 4.9.18-1 (2017-03-30) ppc
GNU/Linux
Follow-up: I updated to 4.9.0-3-powerpc-smp Debian kernel, which is
4.9.25-1 (2017-05-02) and the fault is still the same.
Overnight I also compiled a vanilla 4.11.0 kernel using the Debian
config as a starting point and "make olddefconfig" for a couple of new
config options, booted it today and it gives the same messages.
This is 4.9.25-1 (Debian 4.9.0-3) smp kernel: https://pastebin.com/vq7XQ39U
