Hi,I'm using KNOPPIX_V7.7.1DVD-2016-10-22-EN.iso and having trouble with ttyS0.If I try to do anything with the port (statserial, cu, fire up mgetty) I get:Looking at the dmesg output I'm getting entries like:Code:TIOCMGET failed: Input/output errorFWIW, ttyS1 works but for our purposes we really do need ttyS0.Is there anyway I can disable goldfish on 7.7.1 ?Thanks.Code:[252930.789687] genirq: Flags mismatch irq 4. 00000000 (serial) vs. 00000080 (goldfish_pdev_bus)
