We don't disable futexes with 2.4.2, but some 2.6.x features =20 are disabled and the glibc of linux_base-fc4 doesn't switch to using =20 2.6.x features when osrelease is set to 2.4.2. Additionally futexes =20 are not fully implemented on amd64 (at least not in HEAD). Also you should not focus on libthr, as it is not used for linux stuff. It would be interesting to know where linux-thunderbird locks up. With =20 a ktrace and maybe the output of linuxulator debugging messages we may =20 be able to narrow this down to the real problem. At this point I'm not =20 100% convinced it is a linux problem per se. Bye, Alexander. --=20 I have a very good DENTAL PLAN.
