linux/cygwin build difference

I did one more compile with initramfs and here is the boot message:

You can see the PCI is working at some level. Also it took a few seconds to issue the second boot message after it gave warnings about "hard coded".

Any idea? Thanks!

i would suggest sticking with the linux build tree.. once you get it working, it will be well worth it. however, regarding your problem... it does seem odd. have you ruled out hardware as being faulty? try compiling in initramfs in the linux build and paste your boot output... your problem is rather odd.
