I stripped the timestamp (sed -s 's/\[[0-9. ]*\] //') and sorted the entries of the two dmesg outputs, but I did not find new entries in the diff.
lspci shows that following devices are using the intel_lpss_pci kernel module: 00:15.0 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #0 (rev 21) 00:15.2 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #2 (rev 21) 00:1e.0 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO UART Controller #0 (rev 21) 00:1e.3 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO SPI Controller #1 (rev 21) and I found this in the dmesg log: input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:1e.3/pxa2xx- spi.3/spi_master/spi2/spi-APP000D:00/input/input4 which shows that the keyboard is connected via SPI on 00:1e.3. That explains it. I will upload a fixed initramfs-tools to noble and file a bug against dracut to include intel_lpss_pci. Thanks for your investigation and help. Do you want to help on getting the SRU (see https://wiki.ubuntu.com/StableReleaseUpdates) into mantic? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/2042710 Title: Can't enter cryptsetup password on MacBook Pro 2017 (MacBookPro14,1) due to missing kernel modules in initramfs Status in initramfs-tools package in Ubuntu: Triaged Status in initramfs-tools source package in Mantic: New Bug description: I have a MacBook Pro 2017 (MacBookPro14,1) with an encrypted root partition, which I decrypt via passphrase during boot, at the "Please unlock disk nvme0n1p4_crypt" prompt. Using 23.04 "Lunar" this worked fine. However after upgrading to 23.10 "Mantic", the built-in keyboard doesn't work for entering the passphrase. Quickest workaround: plug in a USB keyboard for entering the passphrase. Workaround: add the following modules to "/etc/initramfs- tools/modules": spi_pxa2xx_platform intel_lpss_pci ... then "sudo update-initramfs -u". I found that both kernel modules were required to get the keyboard recognised in initramfs. I did a bit of digging into what changed for 23.10. It could potentially (?) be commit 2df78bbb143884b9601a32608e12e43d40ccb0b0 "Do not install ARM/RISCV specific modules on other architectures". I had a look into how dracut handles it. Turns out that they specifically include "spi_pxa2xx_platform" after reporting a similar bug report in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=2166209 I don't know how (if?) they handle the 2nd module, "intel_lpss_pci". Anyway, I don't need an immediate fix since the workaround works for me. Just posting this for further investigation, and for any other MacBook Pro users in the same situation. Thanks for working on Ubuntu, I think you're all amazing!
