Thanks, Dan, that's encouraging. When is (and is) this likely to filter
through to those of us who prefer to not patch their own software?
When Avi releases -59 we'll include that in rawhide. If you need the
LBA-48 fix applied to other releases please file a BZ against the
appropriate Fedora release and add a link to this thread in the BZ
report.
Regards,
Dan.
