[Oneiric][PATCH 1/1] UBUNTU: SAUCE: x86: reboot: Make Dell Latitude E6520 use reboot=pci

[Leann Ogasawara]

Hi All,

http://bugs.launchpad.net/bugs/833705

It's been reported that the Dell Latitude E6520 doesn't reboot unless
using reboot=pci.  The following patch resolves this issue and had been
successfully tested by the bug reporter.  I additionally sent this patch
upstream but was given some push back from one of the maintainers
because "we are starting to have something close to a full Dell product
catalog in the system.  I think we need to come up with something more
systematic..."

So with Kernel Freeze looming for Oneiric, the patch being 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.

Thanks,
Leann
