19854	VM lockup when serial port is enabled in file mode to /dev/null	Thomas Dreibholz		"My VM has COM1 enabled, with data to file ""/dev/null"". It boots the RELEASE-12.1 FreeBSD installer CD (i.e. https://download.freebsd.org/ftp/releases/ISO-IMAGES/12.1/FreeBSD-12.1-RELEASE-amd64-disc1.iso). The VM locks up during boot, with high CPU utilisation. Turning the COM1 port off, everything is okay.

Using a file (e.g. /tmp/test1.txt) for output of COM1 works as well."	defect	closed	uart	VirtualBox 6.1.10	fixed	UART, VM lock-up		other	other
