Now that is what I didn't understand... If this is a BIOS issue, then we may
just be hosed. What always makes me wonder is why it works fine with some
kernels and not others. It isn't inconsistent with any 1 kernel. If a kernel-A
boots - then it boots every time. If the kernel-B hangs -- then kernel-B hangs
every time.

What I was exploring is "what the heck is the difference between kernel-A (that
works) and kernel-B (that fails)?" Some code is doing something that causes
this, but I haven't got a clue what code that is. I only see it when I change

However, I don't rule out it just being a screwy bios. This box has worked with
SuSE 11.0-11.3 and with Arch beginning with 200809 and since. The boot issue
only began with 2.6.34X. That's the only reason I think it has to be something
that changed with the software, because the hardware has been consistent throughout.

I'll just relegate the box to using the kernels that work on it and quit
reporting the ones that work and ones that fail. I know that I don't know enough
to debug it further, so we will leave it here. If the dm-devel guys come up with
something, I'll pass that along.
