corrupt fielsystem on a Debian etch system



Hello all,

I'm running a Xen virtualized Debian Etch guest. On friday I had to do
some maintenance work (memory upgrade) and had to shutdown the whole
system. After a reboot one (and only one!) of the Xen DomU does not start
correctly. The System is a Debian Lenny with Xen and several VMs (mixed
Lenny and Etch systems).

A closer look reveals me the following:

==============

It seems some files on this VM are somehow corrupt. But I really do not
know how this can happen or how to repair this system. The biggest problem
here is, that I can not start a package manager because
/usr/lib/libstdc++.so.6 is corrupted...

Does anyone has some clues how to repair this VM apart from reinstallation?

Thx in advance,

Michael
