On my debug build, kinst dies with the following error:

src/emu/devcb.h:2431: void devcb_write<int, 1>::operator()(offs_t, Input, std::make_unsigned_t) [Input = int, DefaultMask = 1]: Assertion `m_creators.empty() && !m_functions.empty()' failed.

The same error occurs with other ATA-based games such as mace and evilngt.

The problem is that abstract_ata_interface_device::device_start tries changing the signal handlers of its attached devices. This was always a problem waiting to happen. It should be able to send the signal straight through the slot.
