I actually just applied the patch proposed by Daniel who created this 
bugreport.

"dmsetup resume" is necessary when the bug is encountered, but the patch 
by Daniel prevents it from happening.

IMO the root cause is the bug in LVM that I referenced in my previous 
post. schroot just happens to suffer from the bug because it uses LVM. 
The workaround in Daniel's patch is actually described here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659762#92

   Are there any

I'm not really familiar with the internals of devmapper or lvm do I 
cannot comment on that.

Cheers,
