From 38cba61bff52f22affa66cc764dab2ac158ab7d3 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Fri, 27 Jan 2023 23:35:47 +0100 Subject: [PATCH] realtek: timer: Register enabled scheduler clock Before calling sched_clock_register(), the timer used to drive the scheduling clock should already be enabled. Otherwise the kernel log will show strange time jumps during, and the watchdog might not be pinged in a timely fashion, resulting in reboots.
