** Description changed: [ Impact ] * Unable to boot from usb for specific intel hardware (GNR) * Especially an issue for ubuntu ISO. [ Fix ] * As done for questing, whitelist the missing module to be included in the initramfs. * This is a similar fix that what was done by dracut [1]. [ Test Plan ] * Build an initramfs with initramfs-tools updated and check that drivers/usb/host/xhci-pci-renesas.ko.zst has been included + Proposed validation plan + [Ubuntu Server OS 24.04.5 HWE Kernel Installation Test Plan] + + [Pre-installation process] + 1.

After looking at the initrd generated, the hwe-initrd is missing kernel/drivers/usb/host/xhci-pci-renesas.ko.zst: $ lsinitramfs casper/initrd | grep kernel/drivers/usb/host/ usr/lib/modules/6.8.0-71-generic/kernel/drivers/usb/host/xhci-pci-renesas.ko.zst usr/lib/modules/6.8.0-71-generic/kernel/drivers/usb/host/xhci-pci.ko.zst usr/lib/modules/6.8.0-71-generic/kernel/drivers/usb/host/xhci-plat-hcd.ko.zst $ lsinitramfs casper/hwe-initrd | grep kernel/drivers/usb/host/ usr/lib/modules/6.14.0-27-generic/kernel/drivers/usb/host/xhci-plat-hcd.ko.zst xhci-pci module is also not there as it's in 6.14 a builtin. As depmod is used to find dependencies across modules, I guess it is missing dependencies for builtins. In 6.8.0 we can find in the associated modules.dep: kernel/drivers/usb/host/xhci-pci.ko.zst: kernel/drivers/usb/host/xhci-pci-renesas.ko.zst But it's not the case in 6.14.0.
