Checkout Linus' current source tree and index it with 'cscope -k -q -R' then search for each place reserve_pmc_hardware is called. My cscope reports "File does not have expected format" and when I hit enter opens to the vim splash. When I hit enter once more, I get what I suspect is the first or second result. When I close this file the cscope ui won't do anything except re-open the first result. If I close cscope and restart with -d I can look for other functions (reserve_pmc_hardware will break cscope ever time in any search field). I cannot reindex if I start with -k -q -R I get the old index (as if I had used -d instead). cscope will only reindex if I remove the cscope.* files and try again. I have attached screen shots of my terminal at each step.

This seems to be a problem on my 32 bit laptop install (running the distro kernel) as well.
