I'll add:

On any system I have ubuntu 9.10 ( ubuntu, xubuntu, etc ) installed and on boot / reboot
the following is present ( df -H ): /var/lib/ureadahead/debugfs

System performance is greatly reduced ( 20% - 40% est ), so far, a simple reboot will remove this entry and performance is returned to normal. The key condition / factor is whether /var/lib/ureadahead/debugfs is present

General system specs are wide: 400Mhz - 3 GHz Intel and AMD 32/64 bit, 256 MB - 4 GB RAM, 10 GB - 500 GB HDD mixed brands.

As reported by others, ureadhead, will fail on boot / reboot as well, with out an failure everything is fine

If I can be of any further assistance, please provide brief debug / test commands / log info request, etc and I'll be happy to provide them.
