Someone replied privately and evidently I didn't make some things clear about what I did/tried. After changing the kernel config, I used appropriate incarnations of 'make buildkernel KERNCONF=' and 'make installkernel KERNCONF= KODIR=' and used 'nextboot -k'. I also tried rebuilding nvidia.ko (including when booted under the profiling kernel) but not surprisingly the resulting file was identical to the original. I've just booted into a kernel with options HWPMC_HOOKS so I'll grab some results here. Meanwhile I'll prepare a kernel with just options MUTEX_PROFILING and if I haven't heard anything different in the meantime, I'll set about checking that out without nvidia.ko.
