Ok, now I feel like I'm taking crazy pills...
The embedded system boots up and mounts the root file system on my host laptop. The 'rc.sysinit' startup script executes the command 'mount -a' which should mount /proc, /dev/pts, and /dev/shm, as listed in /etc/fstab. When executed, that command returns "mount: only root can do that".
When I get to the bash prompt, 'whoami' reports that I am, indeed, root. A 'mount -a' from the command prompt gives the same result; it doesn't think I'm root for the mount command.
I can chown a file owned by root to some other user, and I can create a file or directory in a directory owned by root; so it doesn't always think I'm not root.
Any ideas???
Thanks,

Hello,
I'm trying to build a kernel that mounts a NFS root file system. This is an embedded system; it uses an SMSC LAN91C111 network chip that is hardwired to I/O addres 0x300 and IRQ 5. I've been using the driver (as supplied by SMSC) as a module, and it works fine. Now I'm trying to incorporate it into the kernel build so that I can mount an NFS file system when the system boots.
I've added the source code to the kernel tree, and modified the Makefile(s) and Config.in files so that the driver <<appears>> to be compiled into the kernel. The kernel will load, but the chip is not initialized and the NFS fails.
Since I don't know how to pass the io address and irq number to the kernel, I've hard-coded them into the driver's init function (which I don't see being called).
If someone could point me in the right direction, I'd appreciate it.
Thank you,
