Hi,
I am now running with kernel from backports and it seems to be stable.
However my bluetooth mouse keeps disconnecting after not being used for a short period of time and then reconnecting when moved, slightly annoying.
I don't recall seeing this problem with old kernel when bluetooth worked.
Maybe it did disconnect/reconnect with older kernel as well, but reconnecter faster so I didn't notice.
