can't boot to debian anymore

I cannot boot into debian but rescue system is still working. Please see the below for the output from netconsole.

It seems it cannot start the kernel. Please suggest my current option. Thanks.

Starting kernel ...

I would start with a filesystem check on the USB stick. Could be that it somehow got corrupted and can't load the kernel because of that.

I just spent hours debugging a similar problem. Turns out init=/sbin/init-ro was leftover from the emdebian-squeeze-readonly script, specifically, in the

fw_setenv usb_set_bootargs 'setenv bootargs console=$console root=$usb_root rootdelay=$usb_rootdelay rootfstype=$usb_rootfstype $mtdparts init=/sbin/init-ro'

Once I replace /sbin/init-ro with /sbin/init, all was well again. Wish I'd noticed that earlier. Hope this helps...

fsck the usb drive from another linux box works. Thanks.
