Bug#701953: initramfs-tools: Missing modules prevent passphrase entry with usb keyboard
Package: initramfs-tools
Version: 0.109
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
I have a usb keyboard attached to a system with an unencrypted /boot and a
LUKS-encrypted partition (LVM physical volume) containing the other
filesystems. Today I installed linux-image-3.8-trunk-amd64
(3.8-1~experimental.1). initramfs-tools created a corresponding initrd, as
expected. Booting this kernel/initrd in grub2 resulted in a plymouth passphrase
entry screen, but a usb keyboard that did not work in any port. All keyboard
lights were off. The system was thus unbootable without a non-usb keyboard
(hence critical severity). Without a non-usb keyboard or backup grub entry (3.7
kernel with working initrd), I would have been unable to access my system
without rescue media.
This is a regression from the behaviour of initramfs-tools with linux-image-3.7
-trunk-amd64 (3.7.8-1~experimental.1).
The failure appears identical to this:
http://linux-kernel.2935.n7.nabble.com/PROBLEM-3-8-0-rc4-keyboard-failure-at-
boot-tp585937p587518.html
Workaround is to add the following modules to /etc/initramfs-tools/modules, as
described in the link above:
ehci_pci
usbcore
usb_common
xhci_hcd
uhci_hcd
ehci_hcd
ohci_hcd
usbhid
hid_generic
Once these lines were added, I ran "update-initramfs -u", was able to boot
linux-image-3.8-trunk-amd64 with the new initrd, successfully enter my
passphrase at the plymouth prompt with a usb keyboard, and the system booted
normally.
See also #639876. This report differs in that I have MODULES=most. And this is
critical not wishlist.
