[rtl] Embedding real time linux

[James Cassidy <jcassidy@nova.genesoft.com>]

I'm trying to create a boot disk with RTLinux to embed in an instrument.
But I'm having a problem that I'm hoping someone can help with.

I've created a bash script that creates a minimum root file system 
and compresses it.  I then build a boot disk with the kernel and this
compressed root.  I set the appropriate bits with rdev.

The kernel boots, the ramdisk detects the compressed ram disk image and
starts loading it.  Part way through, error messages start popping up:

end_request: I/O error, dev 01:00, sector XXXXXXX

After lots of these messages, starting somewhere around sector 9XXX and
continuing to sector 21310 (odd numbers only), everything stops.

I'm assuming that 01:00 are the major, minor numbers.  If so they match
the ram device.  But haven't a clue why this error is occuring.  

Would anyone have any wisdom for me on this problem?

Thanks,
Jim.
