I think the problem is because you|ve created the initrd when having root mounted on sda* and usb on sdb* then when you boot from usb it's sda* you can try the root kernel command line option in grub It could be also that you need a delay_use=0 option for usb-storage. you can try init=/bin/sh to get to the small shell and investigate I've noted some of the things I've done here http://84.112.117.162/cgiwiki/moin.cgi/USB-CRYPTO-BOOT but this is my home pc and the ip will change in a year or so I used actually this - http://luks.endorphin.org/dm-crypt and http://feraga.com/node/30 as source I hope it helps regars -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
