Is this an SMP machine? There were problems with that version of the

No, it's a single CPU Athlon 1800+, the kernel is compiled in with support for
SMP system, but that should not have any impact.



I believe people were also having problems running SMP kernels with the
VP patches on UP. Try the latest version. Q3 as of this writing.

Nicolas,
I'll generate a combined patch and let you know when it's ready. In the mean time, could you try increasing the "base_promotion_interval" to about twice the time slice size?
