Dell Latitude E6220 does not reboot with 64 bit kernel
== SRU Justification ==
It's been reported that the Dell Latitude E6220 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 Latitude E6220 models.
== Test Case ==
Without the patch, those with a Dell Latitude E6220 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.
[bug for model E6520 is https:/
When one tries to reboot the Dell Latitude E6220 with a 64 bit kernel from natty it hangs at the very end of the shutdown sequence. The console output is:
* Will now restart
[ xxxx.yyyyyy] Restarting system.
Then nothing happens. One has to force power off.
Sep 12th the E6220 will be back, then I can verify the patch given
