Re: Want uni-processor kernel on FC5 x86_64

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


Workaround to simulate this might be to add the following to the SMP kernel commandline

isolcpus=1

But it seems there is a deeper problem somewhere that it locks up at all.
