As mentioned on Google+, I have a partition that I can no longer mount
normally, containing a lot of my personal data and all backups from
my laptop.
I found now that I am still able to mount it using the 'nospace_cache'
option, but it takes a couple of minutes and I get INFO: task

Hi Arnd,
First things first, nospace_cache is a safe thing to use. It is slow
because it's finding free extents, but it's just a cache and always safe

Wow, that is a crappy driver ;-) Dave Woodhouse was apparently the last
person who understood it and had something to do with it, and that was back
