Kernel 3.19.x & wireless keyboard during startup

[wintonian]

With reference to this thread from getting the module for the Logitech K750 into initramfs originally.

It is the same problem really, i.e. keyboard works in Grub and at login, but i cannot enter password at cryptsetyp although a wired USB keyboard works fine.

user-001@elrond ~$ lsinitrd /boot/initramfs-$(uname -r).img | grep logitech
-rw-r--r--   1 root     root         6996 Mar 18 05:05 usr/lib/modules/3.19.1-201.fc21.x86_64/kernel/drivers/hid/hid-logitech-dj.ko.xz
user-001@elrond ~$

So the module loads, it just doesn't seem to work, and I have issued "dracut -f" just for fun but the keyboard still refuses to work at the cryptsetup prompt and the unifying receiver was plugged in during the kernel update.

Also this still seems to be the case in 3.19.2 kernel.

I suspect somethings broken in the kernel - perhaps?

Hi,
For what is worth, I am seeing the same experience. I tried two 3.19 kernels (the one just released and the other from the testing repo), and neither allows me to type the password at cryptsetup. This is also a wireless Logithech USB keyboard which is otherwise working fine with Fedora 21 and a 3.18 kernel.

Fine I'll open a Bugzilla in a bit then.

Edit:

Perhaps I should of though about looking there first.

#1204392

I'm no expert on the kernel, quite the opposite, but I wonder if this is where it broke?

I see there have been further changes in 3.20 (AKA 4.0).

Has anyone tried to see if this is fixed in F22 - which uses 4.0.0?

[wintonian]

I shall mark this one as solved, not because a fix has been issued but there is a 'fix it yourself' (as opposed to a workaround) type solution.

From the bug report:

This happens whenever the kernel modules needed for the Logitech receivers change. It happened with kernel 3.2 (bug #786303), and now it's happened again with 3.19, which now requires the hid-logitech-hidpp module.

Thomas provided the workaround in comment 4 above, but the fix requires a patch to the dracut package to /usr/lib/dracut/modules.d/90kernel-modules/module-setup.sh to add hid-logitech-hidpp after hid-logitech-dj.

So the relevant part of module-setup.sh should look like:

        instmods yenta_socket scsi_dh_rdac scsi_dh_emc \
            atkbd i8042 usbhid hid-apple hid-sunplus hid-cherry hid-logitech \
            hid-logitech-dj hid-logitech-hidpp hid-microsoft firewire-ohci \
            pcmcia usb_storage nvme hid-hyperv hv-vmbus \
            sdhci_acpi

what does localectl show? It could see your keyboard as being different from what previous kernel saw it.

System Locale: LANG=en_GB.UTF-8
VC Keymap: uk

I'm not sure what you mean??

The problem was that the kernel driver has been changed from 'hid-logitech-dj' to 'hid-logitech-hidpp' for the unifying receiver devices but this hasn't been reflected in dracut/ initramfs.

At least that is my very rudimentary understanding.

This I suspect is the kernel change responsible:
