The errors have nothing to do with ehci patch merges,
(I had tested it on beagle rev c board before posting it out)

Looking into it closely the below two patches are causing this issue:

[...]
commit 498cbdfe62a8330f6c89765bdd15e60328a26511
Author: Patil, Rachna <rachna at ti.com>
Date:   Sun Jan 22 23:46:23 2012 +0000

ARM: AM33XX: Add AM33XX I2C driver support

commit 2faa76196af4b3e93bcb9e38ed9090cbd3b06db3
Author: Patil, Rachna <rachna at ti.com>
Date:   Sun Jan 22 23:44:12 2012 +0000

ARM: I2C: I2C Multi byte address support
[...]

Reverting these two patches I don't see these errors
on my beagle rev c board logs as in here [1]

btw, usb error printed is a musb error not the ehci host error.
