Fresh install with encrypted partition won't boot

Hello everyone,

this is my first post and I hope I chose the appropriate sub-forum.

I created the following partitions during install:
- boot partition
- encrypted (luks) partition with /, /home and swap LVMs

I configured my kernel with:

HOOKS="base udev autodetect modconf block keyboard keymap encrypt lvm2 filesystems fsck"

and compiled it. The first reboot gave me some 'usb not detected' error, so I deleted
the keyboard option and recompiled the kernel. I also configured GRUB according to
the wiki and lsblk -l:

GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda2:main root=/dev/mapper/main-root resume=/dev/mapper/main-swap"

After rebooting once again, I'm now stuck at the passphrase; after typing it in, nothing
happens, not even an error message and I have to hard reset. I suspect it has something
to do with my GRUB config.


This is my first shot at an encrypted system (aswell as LVMs) and I'm pretty much clueless... Any input
would be greatly appreciated.

Re: Fresh install with encrypted partition won't boot

I think this might be the issue:

linux	/vmlinuz-linux root=UUID=e620b9d2-73cc-4b5a-b746-c8793dca81df rw cryptdevice=/dev/sda2:main root=/dev/mapper/main-root resume=/dev/mapper/main-swap lang=de quiet

You should only have one root entry per line (catches me out every time I do this with the auto-generation tool). Or at least that's how it is in my LVM setup. To compare, here's my lsblk with the linux-lqx entry:

}

Claire is fine.
