Public bug reported:
After updating Ubuntu 24.04 LTS to a recent HWE 6.17 kernel, the system
developed a serious regression after reboot.
What I expected to happen:
The system should boot normally, with working input devices and peripherals, as
before the update.
What happened instead:
After reboot, the system became partially unusable. At minimum, the internal
keyboard stopped working. Other peripherals also appeared to be affected,
including the microphone. The mouse still worked, and the display was visible,
but I could not fully determine the exact extent of the breakage from the
broken graphical session alone.
Why I am reporting this generically:
I cannot confidently identify every subsystem that failed. The issue looked
broader than a single device failure, so I am reporting it as a kernel
regression affecting peripherals / input / general usability rather than only
one specific component.
Regression:
Yes. The problem appeared after updating to the HWE 6.17 kernel series, and the
system recovered after removing the problematic 6.17 kernels and going back to
the stable generic kernel.
Recovery / workaround:
I recovered the machine from an Ubuntu Live USB. I mounted the installed
system, entered it through chroot, removed the problematic 6.17 kernel
packages, reinstalled the stable generic kernel, regenerated initramfs, and
updated GRUB. After reboot, the system started correctly again on
6.8.0-107-generic.
