mysterious keyboard, mouse lockups with FC5

[Stephen Liu]

Hi James,

It tooks me more than a week to fine tune my new FC5_64 box.  Now I can
use onboard LAN, onboard sound and adding a PCI-E card without
suffering from PC hanging.

Poweroff without PC power-off is one of the remaining problem on this
FC5_64 box.  The cause is adding "noacpi" on kernel option at boot. 
Without adding it PC will hang frequently.  I don't know whether
upgrade BIOS will be its solution.  OR there is other remedy.

Any suggestion?  TIA
