I've got an issue plaguing me at the moment that I'd appreciate some help with.
I have a system which was previously running Fedora 10, but now uses a Vanilla kernel 126.96.36.199. Everything works absolutely fine, and I've got no problems running the Vanilla kernel.
However, I have intermittent issues on boot, whereby the hard drive partitions are not correctly detected before /root is mounted. The system runs only SATA drives (1 HDD and 3 DVD+-RWs). The hard drive is partitioned into sda1(boot) sda2(swap) and sda3(data). LVMs are NOT in use. The SATA controller is a SiI3114.
Sequence of Events:
1) Boot the system normally n times, grub is run and the kernel is booted absolutely perfectly.
2) Reboot the system on the n+1th time, grub is run on the boot partition, and begins to do it's thing with the initrd image.
3) The init script fails on the line which mounts /dev/sda3 on /sysroot with the error:
mount: error mounting /dev/sda3 as ext3 on /sysroot: no such file or directory.
In the above, 'n' is a totally random number.
I've extracted my initrd image and hacked the init nash script. Using the "access" command, I can see that, on a failure, /dev/sda1, /dev/sda2 and /dev/sda3 are NOT present. A bit weird since /dev/sda1 is the boot partition that started the whole ball rolling.
I'd like to be able to reboot the system if my call to "access -f /dev/sda3" fails. Is this possible? I've tried copying the shutdown executable from /sbin to the initrd image sbin directory and rebuilding the image, but I get "Shutdown: unable to send message: Connection Refused" when that part of the init script is run.
I guess in a nutshell, what I'm asking is: How do I add an executable to my initrd image so that it's available from Nash on boot?

I know this is only a workaround, and the real issue is why the drives aren't detected, but this is an embedded app and the workaround will do until I can figure out what the heck is going on with my SATA drives.
