File kdump-powerpc-no-reload-on-CPU-removal.patch of Package kdump
From: Petr Tesarik <ptesarik@suse.com> Date: Fri, 6 Dec 2019 09:54:57 +0100 Subject: powerpc: Do not reload on CPU hot removal References: bsc#1133407, LTC#176111 Git-commit: d1c4f630f0da0bf43928e3c975f02e832b2df50f Skipping reload after a CPU goes offline does not have any adverse impact, as /sys/devices/system/cpu/cpuX nodes are present for all "possible" CPUs on PPC64. The udev rule for CPU online operation is still needed. If reload is skipped and the system crashes on a hot-added CPU, the kdump kernel fails to get the 'boot_cpuid' after a hot plug and eventually fails (see early_init_dt_scan_cpus() in arch/powerpc/kernel/prom.c file).
