I can boot it hitting SysReq+K, but only in text mode. X start but I can't do login (the mouse moves but I cant enter username and password). Furthermore if I hit some key in GDM I can't switch to text console anymore. If I switch to text-mode after boot all seems to work. Maybe this is related to some important process I kill with the SysReq key. I'm quite confident the system blocks on "Setting consoles fonts and modes.", and thus during the boot script console-screen.h. I'll try to see which commands blocks... BTW, I've tried the serial port in text mode. With the patch, flushing the input results effectively in a complete flush. However after doing the flush I can't read any char anymore without closing and reopening the port. I've verified this behavior both communicating between two serial port and both communicating with an usb-serial device (driver cdc-acm).
