From 96b585267f552d4b6a28ea8bd75e5ed03deb6e71 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 3 Aug 2016 22:20:22 -0400 Subject: [PATCH] Revert "ACPI / hotplug / PCI: Runtime resume bridge before rescan" This reverts commit 16468c783cb4cf72475dcda23fabecb4a4bb0e17. Bisection showed that it was the root cause for a resume hang on a bog-standard all-Intel laptop (Sony Vaio Pro 11), and reverting fixes the hang.
