I did get it from /var/crash/ though - is it more useful? I don't have
vmlinux for this kernel though, but have just built 4.1-rc7 with the
same config, can try to get the crash there.
I've uploaded a crash dump and vmlinux here:

Let me know if it's anything useful or if you need more info.
I've tried running it the same procedure to get one more crash, but it
didn't crash this time.
Instead, btrfs is hanged on any writes - any processes trying to write
get into D state and never return; there is no write activity when
checking for example with iostat. "sync" command does not return.
Reads from this btrfs filesystem are OK.
I've uploaded the output of "echo w > /proc/sysrq-trigger" here:
