I'm seeing this too, as you may've seen in recent list emails. I'm =
trying to
track down where the problem lies, but it's not just you.

I'm compiling natively, so as others have said, it's likely not =
related to
cross-compiling.

I saw this too, and it wasn't initially a problem, but I noticed that =
the
last couple hundred bytes of the binary weren't being copied out,
and hoped that was the problem that was causing the crash. As it
happens, it wasn't, but I determined that the error "Invalid argument"
is a result of a write to the device of smaller than the 512 byte block-
size. If you add a "conv=3Dnotrunc,sync" to the dd command, it will =
fill
out the last block, and write to the disk device without error. (the
notrunc isn't related to the issue, but is in the command I use)
Thanks.
