== SRU Justification ==
It's been reported that the Dell Optiplex 990 doesn't reboot unless using reboot=pci. The following patch resolves this issue and has been successfully tested. Upstream is unfortunately not accepting any additional quirk patches like this as they would prefer to migrate to a more systematic approach. Given that the patch is system specific (ie low risk of regression), precedence for similar quirk patches already existing, and having received positive test results, I feel it should be carried as a SAUCE patch until a more systematic approach can be found which upstream will accept.
== Impact ==
Affects Dell Optiplex 990 models.
== Test Case ==
Without the patch, those with a Dell Optiplex 990 must use reboot=pci as a workaround in order for the system to successfully reboot. With the patch applied, the work around is no longer needed.
== Fix ==
See Comment #9

Machine hangs on "Restarting system" when restarted, and fails to shutdown when sudo halt -n is run. The machine also hung at the reboot screen during the installation of Natty beta 2
