Suddenly cant upload sketch

All of a sudden Im no longer able to upload to the board, error is ‘Board at /dev/ttyACMO is not available’. A full error output is attached.

Things that might be useful to know:
Linux Debian Kernel version 3.2.65-1
Arduino 1.5.7
Arduino UNO, ethernet sheild, linksprite lcd shield
Problem occured when re-uploading webserver example script
No other items connected
Board had functioned correctly earlier when uploading ‘helloworld’ example to same stack to test the lcd shield
Currently cant upload ‘Blink’ script to basic board

Ive restarted the IDE as root and get :
“avrdude: ser_open(): can’t open device “COM1”: No such file or directory
ioctl(“TIOCMGET”): Invalid argument”
Restarted the board, led blinks
Am probably going to remove and reinstall the IDE later unless there are better ideas
