Sorry, can't help you if you don't include ksymoops output (or at least
some more specific problem description).

Need ksymoops info as well.  I don't have any non-ix86 systems to test on,
but at least we should be able to narrow down the problem a bit.  Note
that Andrea Arcangeli does test LVM on Alpha, so I'm surprised there are
major problems.  However, it may be that he has Alpha-specific patches
in his LVM code that are not in the standard LVM sources.

Cheers, Andreas
