Forgot to mention:

- All stations that failed where running a 2.6.21 kernel + CFS v18 (I don't have any stations running a plain 2.6.21 kernel so can't tell)
- Config file can be found at: http://linux-dev.qc.ec.gc.ca/kernel/debian/CONFIG-i686-2.6.21-005
- kernels can be found at: http://linux-dev.qc.ec.gc.ca/kernel/debian/sarge/i686/2.6.21/
