Heheh indeed, this case would require a very big log buffer I guess! But
our setup is not so big, only 4/8 CPUs, not so much RAM and not that
many tasks expected, opposed to a big server with maybe multiple VMs,
containers, etc...

Cool, thanks! If nobody complains or show any reason in that ramoops
shouldn't be changed to deal with multi-chunk dmesg, I'll try to come up
with something then.
