I don't know if this is the same case, but Gerd showed me a migration failure
that might be related.  2.0 seems OK, 2.1-rc0 is broken (and I've not found
another working point in between yet).

The test case involves booting a fedora livecd (using an IDE CDROM device)
and after the migration we're seeing squashfs errors and stuff gently
falling apart.

Perhaps you could try testing workaround patch I sent earlier? It's not proposal for inclusion, just a test patch that seems to fix IO hang for me.
