Not very helpful, I know :(
I'll try rebooting into a kernel with that commit reverted next.
Areca controllers appear to be a bit weird: e.g. they needed special
support in smartctl...

I could set one up, in theory, but the problem is that all my machines
are rather dependent on my NFS-mounted $HOME. Guess where it's mounted
from... in any case, the machine has no serial port, so it would have to
be a usb-serial console, and we know exactly how reliable those are :/
