It says:

puc0: <NetMos NM9845 Quad UART and 1284 Printer port> port 0x<some numbers>
irq 17 at device 7.0 on pci1

UART2: <Non-standard ns8250 class UART with FIFOs> at port1

Pressing Ctrl-T doesen't do anything. The system hangs.

Am I able to stop loading the kernel driver at boot time, and loading it
manually? Then do some debugging?

Thanks,
