Yes, I find x86_64 traces significantly harder to follow. And I miss the
display of the length of the functions (do_md_run+1208 instead of
do_md_run+1208/2043). The latter form makes it easier to work out
whereabouts in the function things happened.

That, plus the mix of hex and decimal numbers..

Plus they're wide enough to get usefully wordwrapped when someone mails
them to you.
