--- Comment #2 from Darren Tucker <dtucker at dtucker.net> ---
This indicates that the Message Authentication Code (ie the packet
integrity check) failed, likely due to a packet being modified in
transit.  The error message has changed due to some infrastructure
changes but this is the same as bug#845 and bug#510.

Things that have been known cause this in the past:
 - buggy or faulty network devices modifying packets in transit
(Linksys devices used to be notorious for it, eg bug#510).
 - buggy NIC hardware, firmware or drivers, particularly TCP offload.
 - bad RAM
 - buggy compilers, particularly miscompiled OpenSSL libraries

I don't recall any instance where it was actually a problem in OpenSSH
itself.  If you do figure it out, please add whatever you find to
bug#845.
