I found one patch that was missing that allows debug configurations to build properly. Heres that patch: --- linux-2.6.21.orig/kernel/latency_trace.c +++ linux-2.6.21/kernel/latency_trace.c @@ -24,6 +24,7 @@ #include <linux/utsrelease.h> #include <asm/uaccess.h> #include <asm/unistd.h> +#include <asm/asm-offsets.h> #include <asm/rtc.h> #include <linux/stacktrace.h> With this patch in place, I am able to build/boot both a 21.1-rt1 kernel with a standard x86_64 PREEMPT_RT+SMP both with and without the usual debug options, so that is great! We did find a regression. I was mistaken earlier when I mentioned our T60p laptops couldn't boot. It turns out that issue was resolved somewhere along the way and our published patches based on 21.5-rt19 do allow the laptop to boot event with acpi=on. With 22.1-rt1 the laptop crashes unless acpi=off. Now that we have your queue we will bisect this and post that fix as well.
