Today it happened again and, as before, it involved the new USB 3.0 DVD drive. The scenario was identical to the first event; i.e., I had to kill handbrake because it had hung on encoding a DVD, and then I had to unplug the drive because it wouldn't stop trying to read the DVD, nor would it eject the media. A few moments later the keyboard and mouse froze, although no flashing lights this time. Tim reports above a similar problem with kernel 3.16.0-71-generic and that he uses 3.16.0-69-generic instead. Although my Xubuntu 14.04 is up to date, Tim is way ahead of me: uname -a Linux Devil-Bonobo 3.13.0-86-generic #130-Ubuntu SMP Mon Apr 18 18:27:15 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux This computer has been upgraded to new kernels numerous times, so I'm sure there are other kernel options in the Grub boot menu, that haven't tried. I should add that I have a 128GB USB 3.0 flash drive that I mount and umount constantly with never a problem, so it may be that the problem resides in the new DVD drive. Later today I will search the net, including the Ubuntu forums to see if I can dig up any more clues or workarounds. Having to reboot every few days is not acceptable. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
