As I mentioned in my reply off list, that triggered a memory that I had 
a similar problem with PE 1850 a couple years ago that turned out to be 
triggered by the Radeon graphics driver, that was solved by switching to 
vesa or fb or disabling X at the console.

Lo and behold, I have 2 nearly identical PE 1950's, one that has this 
issue, and another that does not, and it turned out the one with the 
issues was running gdm at the console!  The one that is not running gdm 
but just a text console never has issues.  So just maybe, that is 
exactly what the problem is.  I have disabled gdm on the console and 
made sure X is not running, will see if that solves the problem.

On the server that has problems, I found that adding kernel params noht 
maxcpu=1 made the system a lot more stable, but did not solve the 
problem completely.  Maybe with disabling X that will no longer be 
necessary, so the full power of the system will be available again.

Running vncserver does not seem to trigger this issue, so is an 
acceptable workaround if I want to do something via the GUI.

For what it's worth, both of my servers are running Ubuntu Dapper LTS 
amd64 with 2.6.15-29-amd64-server kernel.
