No, there is defintely something wrong with how PCI and interrupts are 
set up on the cobalt port that dramatically reduce performance of both 
the network and I/O subsystem compared to the original linux 2.2 kernel 
the qube came with.  I just haven't had time to look into it.

My machine is stable, though.  It has been up for 115 days and was up 
for over 200 before then.  It was rebooted (for what turned out to be 
no good reason) or I would be approaching a year of uptime.  My machine 
runs as a firewall and mail server, with some light file serving for my 
home net, but the performance problems limit it in that regard.
