Symptoms since upgrade to 3.2.0-39-generic two days ago:
System does not shutdown correctly (need to hard shutdown by powerdown). Login lasts horribly long.

This morning I looked into /var/log/syslog and later into dmesg. So I detected this 'BUG' message in snippet below.

[ 66.097491] RIP [<ffff8804045e4020>] 0xffff8804045e401f

Anyone with similar problems?

[SOLVED] -- (quick fix -- not permanently)
Don't know what is going on here in detail. Seems that Rhythmbox is broken.
Anyways: I purged Rhthmbox


$ sudo apt-get purge rhythmbox
and this strange symptoms are gone.
