| |
2.6.27-longterm review patch. If anyone has any objections, please let us know.
------------------
commit b7798d28ec15d20fd34b70fa57eb13f0cf6d1ecd upstream.
Rebooting on the Dell E5420 often hangs with the keyboard or ACPI methods, but is reliable via the PCI method.
[ hpa: this was deferred because we believed for a long time that the recent reshuffling of the boot priorities in commit 660e34cebf0a11d54f2d5dd8838607452355f321 fixed this platform. Unfortunately that turned out to be incorrect. ]
