The problem you are seeing here is probably prep_init in prep_setup.c
not copying the arguments passed by the boot loader into the kernels command
line. Your root=/dev/sda5 is probably ignored.
Look at your early log messages during boot. There should be a line
"Boot arguments: ..." telling you those things seen by the kernel.

In case the arguments aren't as you typed them, try putting the following
lines at the beginning of prep_init:

+       if (r6) {
+               *(char *)(r7 + KERNELBASE) = 0;
+               strcpy(cmd_line, (char *)(r6 + KERNELBASE));
+       }

What hardware is this running on? If it is Motorola VME this failure is only
the starting point and other trouble will follow. There are additional fixes
but I can't verify them against a working source at the moment. test9 and test10
from fmlabs currently both panic during init as soon as the process starts using
the hard drive (this is on a PowerStack).
