It seems I'm being bitten again by this. Last time you kindly helped me
resolve this issue on a Debian Lenny (kernel 2.6.26-2-xen-amd64, lvm
2.02.39-7, kpartx 0.4.8-14+lenny2).

This time it's a slightly older system (Debian Etch, kernel
2.6.18-6-xen-amd64, lvm 2.02.06-4eth1) but in a rather remote location
(at sea). The system is rock solid otherwise and upgrading is quite an
undertaking so if at all possible I hope to be able to resolve this
issue without upgrading.

Any advice you can offer is much appreciated.

kind regards,
Jan
