Hi Joep,
Booting from a snapshot isn't possibly because the snapshot is not
writable and the boot operation writes to the BE. Booting from a
clone is successful because the clone is writable.
The second issue is whether the reboot command understands what
a snapshot is. I see from the reboot man
There are two calls to vfs_rele in the stack trace, may be explaining
why the assertion failed.
Regards,
Andrey

Folks,
I've been seeing this for a while, but never had the urge to ask, until now.
When I take a snapshot of my current root-FS and tell the system to reboot off
that snapshot, I'm faced with an assertion failure (running DEBUG bits) that
looks like this:
r...@codemonkey:~# df -h /
Filesystem
