With Dustin Kirkland's help, I tested out packages based on debian's 2.6.7.2 and 2.6.8 packages; 2.6.7.2 still causes mdadm to segfault for me when incrementally assembling a raid10 array, but 2.6.8 does not. We'll be digging in to find out what portion of 2.6.8 we need to cherry pick to fix this. Thanks for your patience!
