Unfortunatly no. Today, when I haven't worked at 2 am, it happened at 5
am resulting in freeze of desktop except screensaver (which probably
don't issue I/O to $HOME). It happens at least once per day but I
neither know how to trigger it nor what is the underlying issue.
HOWEVER, I did tried in the past to:
- Backup the image on external harddrive
- Loop-mount it
- mkfs.btrfs /dev/my/partition
- rsync -aHAXP back the contents
and it didn't solved the problem.
Additionally very often restarts result in known OOPS bug.
I do have the old image but I've just tried 3.1 kernel when you sent
this message.

I reproduced it on 3.1 rc4. The behaviour is similar except it is
trigger each time I log into account (NOT mount /home - log into
account).
It might have something in common with suspend.

To keep up-to-date:
- It happens at 2 am it results in freeze. To be more precise the
snapshot is scheduled at 2 am and the lock was 2:07 am. The after each
odd reboot the bug is triggered on boot and on each even boot the
computer hangs shortly after logging in. I can still rsync to separate
partition w/out problems in case of even boot.
- If it happens at other time (for certain reasons I haven't reproduced
it with 3.1 - long story why not but I suspect it might correlate to
uptime) the bug may or may not freeze computer.

I still have no idea how to reproduce it but:
a) It happens on both clean 3.1 kernels as on 3.0 with various patches
b) The snapshotting is not a cause (it was coincident)
c) It usually happens a few minutes past 3 UTC. I have no idea what is
casuing this but it is consistent.
d) Compression is not a cause
Best regards

Sorry for spamming in this thread but I'm trying to post my findings in
hope that somebody will understand what's going on.
Recent crash gave some valuable information IMHO:
1. I started the autocompletion of path in zsh
2. At some point the zsh hanged. In ps the process was listed as
runnable
3. Any access to root volume (the one that zsh was trying to readdir)
finished in hang.
4. I was able to access the child volume (/home)
5. After some time the bug is hit. At this time strange things happens
(screen freeze etc.). I guess that there is some strange interaction
between KMS, X and now-hanged composite manager
Next time it happend (also during listing root directory of volume 0) I
observed the following thing - I can log out and unmount home but the
volume 0 remains busy and cannot be unmounted.
Things to consider:
- It is not enabled/disabled by any mount option
- Is it triggered when the parent volume (say volume 0) and child
volume are both mounted?
- Which case is it failing (I've tried to add printk but I cannot find
the option in printk to print u64)
- Why it happens only during night?

I cannot reproduce it when the parent volume is not mounted (snapshots
are to subvolume)

1. Once the blank screen happened ot 23:00 UTC instead of 03:00 UTC
2. I tried to disable the caches
3. I tried to rsync via ext3 + btrfs-convert. I noticed something - in
old fs the df looked like:
Data: total=30.01GB, used=28.42GB
System, DUP: total=8.00MB, used=4.00KB
System: total=4.00MB, used=0.00
Metadata, DUP: total=1.00GB, used=199.47MB
Metadata: total=8.00MB, used=0.00
on new one (with ext3 image):
Data: total=33.33GB, used=20.52GB
System: total=32.00MB, used=4.00KB
Metadata: total=16.64GB, used=11.36GB
and without:
Data: total=33.33GB, used=20.04GB
System: total=32.00MB, used=4.00KB
Metadata: total=16.64GB, used=10.88GB
Given that lzo compression was used about 4 GB data difference was
expected (difference depending on mount options on rsynbc). However:
1. What is DUP?
2. Why metadata is so big on convertion from ext3 while data is small
(the sum is about right - 31GB vs 28.5GB)?

That should be a) b)
4. I think it triggered a bug with data loss - the new data was not
written to disk despite being visible from userspace after mount during
the same mount.
