I'm seeing an application hang on termination in OVMF. I'm told this app
does a "far return" instead of the using system function if that is
important. GDB (no symbols yet) shows that the system is reading i/o port
0x3fd and testing bit 0 (COM1's LSR register "data available" bit).
I'm guessing an assert fired in the EFI code and some debugger is being
started on com1. I've tried using "qemu ... -serial stdio" and I see some
activity when OVMF starts, but nothing when the application hangs.
Any suggestions?
