Hi,
since the upgrade to FC5.x86_64 (from FC3.x86_64) Thunderbirdsometimes locks up when downloading large emails (not alwaysreproducible), Firefox frequently hangs (irreproducibly) withoutapparent reason. Starting both programs with "strace -f ..." showsthat the last system call before lockups are futex syscalls. So Ithought there might be some race condition? Maybe it has to do withthe SMP kernel used by default in 64bit FC5? Is there a way to get a"FC5.x86_64-standard kernel" without SMP?
Regards,

Similar symptoms for me -- including occasional core dumps onthunderbird startup (and other odd behavior) -- turned out to be a badDIMM. It failed memtest86 repeatedly.

Checked that for my computer too. memtest did not report any errorsafter running for three days consecutively.
