I found a compilation error while compiling this new version of the rt
pach. I guess the following line is enough for you to trace the problem:

kernel/trace/trace_events.c:49: error: ?function_trace_stop? undeclared
(first use in this function)

It seems that an 'extern int function_trace_stop' is missing somewhere...

Hi Luis,

What arch did you compile this on? I did a make allmodconfig on x86_64
and it compiled to completion. I also ran this on x86_64 and i386 boxes
(a more natural config).

Could you send me your config and tell me what arch you compiled this for.

Thanks,

-- Steve

Luis, I just released a -rt11 that should fix this for you. Can you
download it and give it a try.

Thanks,

Hi Steve,

just recompiled it and, although I did not really tested it (just booted
the new kernel), it seems to works like a charm ;)
