I got this lovely kernel panic while copying lots of files (backup) from an external HDD (ext3) to my internal HDD (btrfs) using the Dolphin file manager (KDE):

If I read that correctly (from bottom to top), I'd say btrfs is causing the problem, without actually knowing all those kernel functions.
Can someone with more kernel knowledge confirm this?
The kernel version is 3.8.4-1-ARCH, the system has been updated a few hours before the crash (no kernel update, just other packages).
It was installed from the current Arch install ISO just a few days ago and I haven't really done anything except installing packages, editing important config files and restoring the backup.
Now what to do about this?
Is this something I should directly send to the btrfs developers or do I need to run some analysis software first?
I haven't yet checked if there is file system corruption but the system was able to boot.
EDIT: btrfsck completes without errors.
Journald (the "syslogd" from systemd) did log nothing of interest at the time when the panic happened.
I'm going to copy the exact same files again to check if the panic is reproducible.
EDIT: I was not able to reproduce it.
Is there any program or kernel module I can run while doing this to produce helpful debug information?
Thanks in advance!
