Public bug reported:
When trying Ubuntu Core with the pc-kernel snap, the system showed
'cannot find writable partition'. The system was stopped at the initrd
stage and didn't accept any input.
My system is using a NVMe disk and it seems the pc-kernel doesn't
provide the related modules in its initrd. Also, it's not possible to
enter the initramfs environment because of the lacking of USB HID
modules.
Is it possible to include these two categories of drivers in the initrd
of pc-kernel, please?
Verified both 4.4 and 4.15 (track 18) have the same issue.
$ squashfuse pc-kernel_162.snap pc-kernel
$ lsinitramfs pc-kernel/initrd.img |grep -E 'nvme|usbhid'
[nothing is showed]
$ fusermount -u pc-kernel
$ squashfuse pc-kernel_165.snap pc-kernel
$ lsinitramfs pc-kernel/initrd.img |grep -E 'nvme|usbhid'
[nothing is showed]
$ fusermount -u pc-kernel
