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 ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Summary changed: - Please include modules for NVMe and USBHID in pc-kernel snap initrd + Please include modules for NVMe and USB HID in pc-kernel snap initrd -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1802260 Title: Please include modules for NVMe and USB HID in pc-kernel snap initrd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1802260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
