Hello,

I have a problem when using "nanosleep()". I want to sleep for 20 ms, so I call
nanosleep() with 20.000.000 ns. My system tick is 10 ms.
Result is : the thread is sent to sleep during 30 ms...
I tried to trace the problem, adding traces (diag_printf) in function
cyg_timespec_to_ticks() (/compat/posix/<version>/time.cxx), to output the result
 (number of ticks) to the console.

When called with 20.000.000 ns, this function returns 3 ticks, which is wrong.

When traces are added to this function, in "if (roundup)..." the result is ok :
2 ticks.

I can't figure the origin of this problem. bug compiler ? mismanagement of cache
 ?

thanks for helping.

Bruno Aubert.
