Subject: ext4_free_inode:319: comm krunner: bit already cleared for inode 6293718

For the following 3 errors I think the last 2 are related to the fact,
that I'm booting a Gentoo Linux (kernel 3.7.1) from an external USB 2.0 drive,
but the first error, is that related too to the external drive itslef ? :

Well, what the error message means is that the kernel has detected an
inconsistency in the inode allocation bitmap.

Could this be called by an error to the external drive? Certainly.
It could also be caused by the drive getting pulled before it was
cleanly unmounted at some point in the past, and (especially if this
drive was using flash) the inode allocation bitmap got corrupted.
