Oh Pavel, this is more a whinge than a bug report.  You know better ;)

- How much memory does the machine have?

- UP/SMP/preempt?

- What do vmstat and top say?

- Did it happen in 2.5.64?  2.5.63?  2.4.20?

- Does it get better if you renice stuff?

- What steps should others take to reproduce it?

etc, etc, etc.
