[Bug 1412077] Re: HID USB keyboards not working in initramfs
By comparing -43 and -44, I noticed that no hid modules are present at
all in the initramfs generated for -44 kernel.
Several other module directories are completely missing, although the
kernel configurations are the same.
Is it possible that the correct generation of the initramfs depends on
the kernel running when generating it?

Title:
HID USB keyboards not working in initramfs
Status in initramfs-tools package in Ubuntu:
New
Bug description:
This bug might either be in the kernel extra package or initramfs-
tools, can't decide.
I have tested all following version of the kernel:
- linux-image-3.13.0-35-generic
- linux-image-3.13.0-36-generic
- linux-image-3.13.0-37-generic
- linux-image-3.13.0-39-generic
- linux-image-3.13.0-40-generic
- linux-image-3.13.0-41-generic
- linux-image-3.13.0-43-generic
- linux-image-3.13.0-44-generic *
In all of them except latest (-44), if the corresponding -extra
package is not installed then USBs keyboard will not work (and display
mode will also not be set correctly, although it's a separate issue).
I have narrowed down the issue to the fact that hid, hid-generic and
usbhid modules are missing and thus not loaded.
