I doubt that the AMD K6 is the problem, although there is always plenty 
of room for error with the variety of motherboards and BIOSes out there. 
Over the last 4 years, I have installed various versions of Red Hat and 
Fedora Core Linux on a no-name 600 MHz AMD K6 machine with absolutely no 
difficulty. When I get a chance later this week, I'll try installing 
BDI-4.30 to it just to be sure. Note that 128MB of RAM isn't very much 
memory. If you're unlucky the system will start paging to disk with an 
attendant hit in performance.

I have no experience whatever with LVM (although I've used the 
equivalent functionality on Silicon Graphics' commercial version of Unix 
known as IRIX) but when I search Google on combinations like "lvm 
install debian" and "lvm problem debian" I get plenty of hits. Since the 
BDI is based on the Debian kernel and packaging, I'd try to reduce the 
problem to its simplest form by first doing a trial install of the 
latest stable version of the Debian distribution to make sure I could 
get it running over LVM2 and only then try installing the BDI with LVM2. 
I suppose it is possible that the real-time extensions added to support 
EMC could interfere with LVM, but Paul's already pointed out a more 
likely possibility.

It's just my 2-cents worth, but I think EMC should run on its own 
dedicated host, in which case I'm not sure LVM buys you much anyway.
