I've reviewed my changes but haven't found anything suspicious. Could you please provide: - dmesg from both cold start and kexec, both non-CCF and CCF version, - contents of /sys/kernel/debug/clock/summary (non-CCF) after boot/kexec, - contents of /sys/kernel/debug/clk/clk_summary (CCF) after boot?
