I've filed a bug in the kernel bug tracker, I think we could use a central place to track issues: http://bugzilla.kernel.org/show_bug.cgi?id=9329 I'll try to find time to look into this unless someone knows offhand where the problem is... Thanks, -Eric (p.s. should I get ext[234] bug mail routed to this list, or would that be annoying?)
