Hi!
When I boot my Ubuntu Edgy Eft installation with an external drive
attached it comes halfway through the boot process and then the light
starts to flash. I get buffer I/O-errors in dmesg. When I detach the
drive and reattach it, it seems to work and I can access it.
The problem is that I'd like to be able to boot from the drive.
Is there a solution to this that I've overlooked?
Many thanks in advance,
Magnus
