Description Eugene Teo (Security Response) 2008-12-03 21:20:10 EST
From Alan Cox:

Looks like libata needs to enforce sensible minimum timeouts on SG_IO
requests otherwise the code below (especially run ten at a time) which I was
using to try and duplicate the kerneloops logged errors produces long spews
of errors and forces the drives into PIO run as any user..
Comment 3 Eugene Teo (Security Response) 2008-12-08 22:12:00 EST
Consensus is to enforce a minimum 7 second timeout (which is the timeout windoze uses for general commands on ATA).

You need to be able to open the cdrom device (i.e. login as a normal user from the console and then access it via ssh) or access to /dev/sg* which is root only in all sane systems.
