Anybody know the reason RedHat decided not to support the <br>
VIA Eden Processor?<br>
<br>
cat /proc/cpuinfo<br>
processor : 0<br>
vendor_id : CentaurHauls<br>
cpu family : 6<br>
model : 13<br>
model name : VIA Eden Processor 500MHz<br>

I am testing, (using ayplus kernel) and get the following during
bootup:<br>

FYI.<br>
Replying to my own E-Mail after running <br>
<font face="sans-serif">2.6.32-71.24.1.el6 from SL. I can report
that I have<br>
been having lockups (hangs) on three different via centaur

The hangs require power cycling the boxes.<br>
