Officially, it means there's something wrong with your CHIP ram.
During startup, your Amiga checks how much CHIP ram there's
available. If it's less than 512K (I think) your screen turns
green, the LED blinks 11 times, and another reset is initiated,
often resulting in the same trouble.

Now comes the strange part. I have had the same experience after
I swapped my 68000 with an 68010! I just couldn't believe it had
to do with my CHIP ram chips. So I pressed a little on my 68010,
pulled it out a tiny little bit, pressed it again etc. and when
I turned my Amiga back on, everything went fine! Then I decided
to put my 68000 back in, and my screen turned green again. I had
to perform the same ritual as with the 68010 to fix it.

A friend of mine had to pull the ROM chip in his Amiga a little
in order to fix the same problem.

So I think your CHIP ram chips are one of the last places you will
find the problem.
