Hello,
recently I bought a new Qnap device (TS-219p II, the one with the USB
3.0 ports) and tried to install Debian on it. (also see the thread [1]
on the debian-arm mailing list) The Debian installer couldn't
successfully finish it's job on the device because - as we found out -
the PIC on at least this hardware revision has a watchdog which resets
the device after 5 minutes if enabled.
The solution Qnap used to solve this is simply disabling the PIC
watchdog using their own drivers and a binary called "pic_raw". Since
qcontrol is the solution on Debian used to communicate with the PIC, I
added an option to disable the PIC watchdog.
I don't know if the watchdog also exists or is enabled by default in
other Qnap devices or hardware revisions but it would probably be a
good idea to disable it at boot time for at least this device. Please
find the patch for the added lines of code attached.
