On second thoughts I'm not sure about the second one.

What actually starts the watchdog in the first place?

I was assuming it was the factory provided kernel/userspace, and that
the issue was that you booted the factory software, which starts the
watchdog and tickles it as necessary. But then you soft reboot into
debian-installer which leaves the watchdog running but unpoked => reset.
But then once you got it installed when you booted it under Debian
nothing would start the watchdog and everything would be ok.

Or is it the case that the factory provided *firmware* starts the
watchdog and therefore expects that the kernel and/or userspace needs to
keep poking it?

If it's the former then we only need
debian/udeb/debian-installer-startup.d/S99qcontrol. If it's the latter
then we need both as you say.

Ian.
