MUTEX_PROFILING changes the kernel ABI so modules that are not compiled

your kernel + modules together then it uses the kernel config file for
both so they are compatible, otherwise your modules only are built with
default options. So, if you have any other modules apart from nvidia
then use make buildkernel for those, and add -DMUTEX_PROFILING to the
CFLAGS of the nvidia build and try that. It may still not be enough
since nvidia is a wrapper around a binary module, so you may also need
to revert to nv.

Kris,
Success, I hope. I noticed that the duration of the pause when the
stuttering occurs is obviously magnified, I'd guess probably by approx a
factor of 5. e.g. normally stuttering interval is quite short, perhaps
50-100ms at a guess, with debug.mutex.prof.enable=1 duration of stutter
might be 200ms or so. I understand that this is to be expected, just
want to let you know.
Could you please confirm that I'm following correct procedure to obtain
results, then I'll endeavour to capture logs for the other freezes that
I witness. And of course let me know if you want anything specific from
me.
Yeah, this shows things like contention between the mouse device and
other parts of the kernel that still require the Giant lock in 6.x. It
is not likely that these will be fixed in 6.x but most of them are in
7.0, so you should obtain better performance by upgrading to 7.0.
