FC3 kernel 2.6.10-1.770_FC3 unable to boot from USB HD

[Anthropic Principle]

Hi all,

I configured my FC3 box (kernel 2.6.9-1.667) for booting from USB hard disk
as described on http://simonf.com/usb. The kernel 2.6.9-1.667 boot from the
USB HD unit without problems and all work flawlessy.
Yesterday I tried to up2date my FC3 box and so I upgraded the kernel to the
2.6.10-1.770_FC3 but even done again the procedure of rebuilding the initrd
image (as described on http://simonf.com/usb) the new kernel still doesn't
boot giving everytime an early mount error (mount: error 6 mounting ext 3).

Any suggestions in order to solve that problem ?

Many thanks,

AP
