+Subject: [PATCH 054/347] cpufreq: drop K8's driver from beeing selected
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+Ralf posted a picture of a backtrace from
+
+| powernowk8_target_fn() -> transition_frequency_fidvid() and then at the
+| end:
+| 932         policy = cpufreq_cpu_get(smp_processor_id());
+| 933         cpufreq_cpu_put(policy);
+
+crashing the system on -RT. I assumed that policy was a NULL pointer but
+was rulled out. Since Ralf can't do any more investigations on this and
+I have no machine with this, I simply switch it off.
