ide-cd locks up under 2.5.44

[Thomas Molina]

My hardware is an A7V133 with KT133 chipset, 82C686 southbridge, Athlon 
1.33 GHz processor.  System is RedHat 7.3-based.  

I've built 2.5.44 with ide-cd both built in and modular.  Any attempt to 
load the module, access a disk, or boot with ide-cd built in locks up the 
machine.  If I use modprobe, the modprobe process gets stuck in D state.  
In any of these cases I get an endless stream of:
