My experience with this bug has been severe and painful.  On certain
boxes, both Intel and AMD, I can make it happen every time, using this
process:

1. install 7.10
2. upgrade 7.10
3. change /etc/apt/sources.list to point to hardy, not gutsy
4. apt-get update
5. apt-get dist-upgrade

At this point these boxes will appear to run fine, but certain processes
will experience bus errors.  A reboot will often fail to boot completely
(/bin/sh get bus errors).  The problem appears to be that glibc was
corrupted during the upgrade process, so everything which depends on it
will get bus errors.  I managed to rescue a box in this state by booting
off the 7.10 CD, copying libc from the CD over the one on the disk,
which was enough to get debusums and apt-get to work.  Then I could use
debsums and apt-get to reinstall any packages which were damaged.  I now
use debsums between steps 4 and 5 whenever I upgrade a box.  Mostly it
is fine, but sometimes packages (various ones, but usually the list
includes libc) fail the debsums test; an "aptitude reinstall " before
booting sorts them out.

All the machines where this problem occurred were installed with a small
/boot as ext3 and / as xfs.  I dunno if that's a factor.  Some machines
never showed this problem.  It's becoming less of an issue now that
8.04's out, and the wave of upgrading 7.10 boxes has passed.
