There are problems with initial ramdisk support on Linux-2.3.36. Upon boot, I get 'RAMDISK Image found at 0'. Then a get a panic because it's not able to mount root. It can't mount the ramdisk.
If I boot the machine into Version 2.2.6, I can use the same script to make a ramdisk image that boots 2.3.36. In other words, 2.3.36 doesn't make a bootable ram disk, but once there is one, the new kernel will mount one.
This is the make ramdisk script which has been working all along until 2.3.35 and 2.3.36.
#!/bin/bash # # This installs the kernel on a system that requires an initial # RAM Disk and with an initial SCSI driver. #
