I haven't seen this issue ... but it might actually be sleeping.
CentOS-4 uses a 2.6.9-x kernel that is much better at doing what your
BIOS says for power saving mode than 2.4 kernels were. I would first
check the sleep settings in the BIOS of the problem machine.
If that doesn't work, you try turning off the apmd and acpid services.
Also, to really search for fixes ... the exact hardware that is having
problems might help.
