This sounds like the initramfs doesn't have the appropriate modules built into it. I suspect that your /etc/initramfs-tools/initramfs.conf has MODULES=dep. You should try changing that to MODULES=most; and then rebuild the initramfs using something like: update-initramfs -vu; This should provide information on the modules that are being added to the initramfs, which should include the lvm modules and the ehci modules. [The missing ehci/ohci modules are likely what is causing your USB keyboard to not work.] -- Don Armstrong https://www.donarmstrong.com The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair. -- Douglas Adams _Mostly Harmless_
