Machines with select SiS chipsets crash upon hard reset

[cartifanwlr]

What happened?

The following SiS chipsets:
SiS 5511
SiS 5571
SiS 5581
are affected by this crash.

Picking any machine using this chipset will also break any subsequent configuration manipulations unless changed from outside the emulator, such as a direct settings call through the command line. Exiting a machine using these chipsets will also take a while to shut down the 86Box process, as the emulator seemingly crashes in the process.
