From 07bbe3fd0704ab47d365756a31f45a86e3b45c0a Mon Sep 17 00:00:00 2001 From: Lucas Karpinski Date: Tue, 9 Jan 2024 10:20:50 -0500 Subject: [PATCH] arm64: dts: qcom: sa8540p-ride: disable pcie2a node pcie2a and pcie3a both cause interrupt storms to occur. However, when both are enabled simultaneously, the two combined interrupt storms will lead to rcu stalls. Red Hat is the only company still using this board and since we still need pcie3a, just disable pcie2a.
