[Bug 1275227] [NEW] Computer froze completely upon ejecting firewire external hard drive

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Firewire 800 hard drives have been plugged in and out of this macbook
pro 8,3 laptop running ubuntu 12.04 many times. Today, I plugged in the
drive, copied a number of files into it, and upon pushing the eject
button in nautilus (as usual), the computer froze:  mouse didn't move,
couldn't switch to a tty to kill e.g. a rogue program, nothing. After a
few seconds, I heard the fan going full speed, indicating that a program
got stuck at 100% CPU usage. After a hard reboot, all is back to normal.
First time this happens in the 2 years I've been using this laptop with
ubuntu 12.04.

Thanks for looking into this.
