Hi folks,

Just a quick note that quite rarely I see the new in-tree ssh (well, the
kernel) on my alpha spit out thousands of lines of unaligned accesses,
with only ever two pc's:

	pc=0x12001b95c 
	pc=0x12001b9b0 

and these are in the swap_bytes function (kinda funny that when you
think about it!):

	000000012001b900 t swap_bytes
	000000012001b9c0 T cipher_mask1

I installed the new ssh on October 7, and I couldn't count the number of
times I use ssh a day (cvs stuff, etc) and I've seen this maybe three
times all up.  I haven't looked into this at all yet - it's sleep time
but I want to get a note of the problem down while I remember and will
have a look myself if no one beats me to it.

Simon.
