Hello everyone. I have a raspberry pi 3b arm64 sd card which I recently upgraded in stages from jessie to chimaera. This card has the second partition encrypted, so I need an initramfs to decrypt it.
The problem is that my usb keyboard doesn't seem to be detected in the initramfs. Once I unlock the partition from the serial console, boot proceeds as expected, and everything is fine. In /etc/initramfs-tools/modules I have: # List of modules that you want to include in your initramfs. # They will be loaded at boot time in the order below. # # Syntax: module_name [args ...] # # You must run update-initramfs(8) to effect this change. # # Examples: # # raid1 # sd_mod evdev ecb xts # USB keyboard at boot usbhid hid hid_generic ohci_pci I doubt I need ohci_pci for the rpi3, but I saw references on the web stating that it is needed for a usb keyboard, so included it just in case. The screen during the boot process until the unlock prompt says: [ 7.851176] hub 1-0:1.0: 1 port detected Begin: Loading essential drivers ...

I do see later on that after the root fs is mounted, udevd is started. Also, if I boot with the keyboard unplugged, login, look at lsmod, plug the keyboard again, and look at lsmod again, no new modules are loaded, but the keyboard is detected. So, I think I have all necessary modules in the initramfs, but no udevd. Should udev be in the initramfs? If yes, what should I look at to find out why it isn't in the initramfs. If udevd shouldn't be in initramfs, then something else would have to detect devices on the usb bus in the initramfs. What is that something? This used to work perfectly fine under jessie. If more info is needed, I'll be happy to provide it. Thanks in advance for any tips. If this is documented somewhere, and I haven't been able to find it in my research, a pointer to that documentation would be good enough.
