[gentoo-user] Internal error: Maps lock 14270464 < unlock 14274560

Hello,
After a recent new gentoo install on a lenovo laptop I get during booting:

Filesystem isclean
 * Remounting root filesystem read/write ...
 * Setting up the Logical Volume Manager ...
     Internal error: Maps lock 14270464 < unlock 14274560
     Internal error: Maps lock 14274560 < unlock 14278656
     Internal error: Maps lock 14278656 < unlock 14282752
     Internal error: Maps lock 14282752 < unlock 14286848
     Internal error: Maps lock 14286848 < unlock 14290944
 * Setting up dm-crypt mappings ...
[snip]
Filesystem is clean

I don't find other messages in /var/log/messages. Also the system seems 
to run fine. Has anyone seen these messages? Are they a false positive?

Thanks,
