Well I'm not surprised, hppa is one of the sole architecture still using linuxthreads,
Not exactly, kfreebsd-i386 and kfreebsd-amd64 also use linuxthreads add-on, there is no problem shown on them.
and probably rwlock/mutexes are different enough so that seeing one of them like the other makes odd things, whereas NPTL has some kind of overlapping semantics on both that if it doesn't do the right thing, doesn't break mutexes too much ;) (I'm just guessing the the overlapping bits, but I really mean that hppa *is* different wrt locking).
My guess is the difference between i386/amd64 and hppa is a need for kernel support for compare-and-swap. On hppa, there have to be syscall, which may easily lead into rescheduling, race condition
is just hitted more freqently on hppa. Anyway, it is only guess, build on hppa will show whether it would solve the problem. Petr -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
