Want uni-processor kernel on FC5 x86_64

[Harald Grossauer]

Hi,

since the upgrade to FC5.x86_64 (from FC3.x86_64) Thunderbird sometimes 
locks up when downloading large emails (not always reproducible), 
Firefox frequently hangs (irreproducibly) without apparent reason. 
Starting both programs with "strace -f ..." shows that the last system 
call before lockups are futex syscalls. So I thought there might be some 
race condition? Maybe it has to do with the SMP kernel used by default 
in 64bit FC5? Is there a way to get a "FC5.x86_64-standard kernel" 
without SMP?

Regards,
Harald
