There was a report on -current a while ago that a preliminary patch to fix the non-threadsafeness of mmap(2) MAP_FIXED also makes flash9 work, http://lists.freebsd.org/pipermail/freebsd-current/2007-August/075968.html a fix for that seems to have been committed (kib 2007-08-20) and also mfc'd to RELENG_6 by now (kib 2007-09-09), so, can anyone running either verify that flash9 still crashes for them? Just wondering... Juergen
