Is your virtual serial port the console ? Also when you say "lost remote access", at what point do you lose remote access - what is the last thing printed to the console. What if anything is logged on the monitor if one is plugged in and does it boot fine with the patch but without console on the serial port ?
Is the virtual serial port a standard PC serial port (or appearing as one) and using the standard drivers or is there anything else loaded/special modules in use for it ?

Strange as it simply moves a few flags around. That ought to make it easy to figure however.
