I can't get it to run on x86_64. The kernel won't build with "voluntary preemption" enabled, it's complaining about mce_read_sem being undeclared. Including linux/semaphore.h in arch/x86_64/kernel/mce.c does get the compilation past that point, but later on mtrr and kprobes won't build. I can turn those off, but the build stops on kernel/printk.c with a "console_sem undeclared" error. Everything builds fine with "real-time preemption" enabled, though the linux system as a whole still won't run, as init crashes on startup (kernel panic). I saw earlier postings on lkml related to RT and x86_64, but unfortunately the suggestions made, such as turning off latency timing, didn't help. I tried this on a dual Xeon HT server with SLES 9.1 64bit installed (config has SMP/SMT set to yes). I used the 2.6.13-rc4 kernel patched with realtime-preempt-2.6.13-rc4-RT-V0.7.52-10. Any suggestions or any extra info I've missed would be appreciated.
