Could well be an io error on the snapshot LV but then we should have a related entry in the syslog. If you are able to read the snapshot fine (for eg. with=20 (dd if=3D/dev/SNAPSHOT of=3D/dev/null bs=3D1024k), I assume a reiserfs er= ror. If reading the snapshot LV fails, let's go forward analyzing LVM, if not there might be a reiserfs fix for that.
