  On specific intel hardware (GNR), the Ubuntu ISO 24.04.3 doesn't boot when selecting the hwe kernel.
  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.
