| Subject: x86: Make Dell Latitude E5420 use reboot=pci |
| |
| From: Daniel J Blueman <daniel.blueman@gmail.com> |
| |
| 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. ] |
