This is a note to let you know that I've just added the patch titled clk: qcom: apss-ipq6018: mark apcs_alias0_core_clk as critical to the 6.0-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: clk-qcom-apss-ipq6018-mark-apcs_alias0_core_clk-as-c.patch and it can be found in the queue-6.0 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 597c8d95bbdea21b3b4a70470e65aa1c34d6d412 Author: Robert Marko <robimarko@xxxxxxxxx> Date: Fri Aug 19 00:06:22 2022 +0200 clk: qcom: apss-ipq6018: mark apcs_alias0_core_clk as critical [ Upstream commit 86e78995c93ee182433f965babfccd48417d4dcf ] While fixing up the driver I noticed that my IPQ8074 board was hanging after CPUFreq switched the frequency during boot, WDT would eventually reset it. So mark apcs_alias0_core_clk as critical since its the clock feeding the CPU cluster and must never be disabled.
