It's odd that there is no output from the kernel at all, which
rules out most of the options that change, as they should only
have an effect later during boot.
One thing I noticed is that the last successful boot has a kernel
image size just under 32MB for the vmlinux, while the failing
configurations have more than 34MB.
I looked at the loadaddress as well:
11:43:57.119234 Filename '536723/tftp-deploy-j462agcw/kernel/Image'.
11:43:57.122622 Load address: 0x2000000
11:43:59.708404 Bytes transferred = 34361856 (20c5200 hex)
...
11:43:59.814346 Filename
'536723/tftp-deploy-j462agcw/ramdisk/ramdisk.cpio.gz.uboot'.
11:43:59.814638 Load address: 0x4000000
11:44:00.447924 Bytes transferred = 8517374 (81f6fe hex)
So the ramdisk and the kernel overlap when the kernel is larger than 32MB!
