 Good, sounds like there's not likely a memory issue then (it will usually
 fail within the first couple tests)

 RS32, a null modem cable and the RS232 extension of my shuttle.

 computer running HaikuOs without emulation.

 Actually, I don't think that will work. In order to do serial log capture,
 you will need a real COM port on the motherboard in order to connect to a
 second computer. Using a USB adapter requires a driver that uses the USB
 stack to communicate with the device. The USB stack cannot actually run
 while in KDL (because KDL halts all execution of the OS, drivers, etc.),
 which is also basically why you're having issues with your keyboard.

 If your computer has PS2 ports, then you should attempt to use a keyboard
 attached to that - if it does not, there are some options for having the
 BIOS take control back of the keyboard, but I think that only works when
 it is connected to a USB1.1 hub or something?
