What kernel version is this? Could you try with 2.6.6-mm4 if it was
less recent than that?

Some instrumentation is likely in order. 2.6.6-mm4 has schedstats,
which you should log to get us enough information to do something about
this performance problem. Logs of vmstat, top, and snapshots of kernel
profiles, /proc/vmstat, and /proc/meminfo may also help.
