The kernel in linux- image-3.13.0-101-generic_3.13.0-101.148~lp1649326Commit3f049ea_amd64.deb fails to boot, but in different ways that seem to be somewhat random:
* Sometimes the warnings "Failed to get file info size" and "Failed to alloc highmem for files" appear. * Sometimes, when launching from rEFInd, the above messages appear along with ASSERT messages from the UDK2014 tool kit used to build rEFInd, as shown in boot-failure.png. * Sometimes the message (shown in boot-failure.png) "ASSERT fsw_efi.c(674): CR has Bad Signature" scrolls across the screen and fills it entirely. (Note that fsw_efi.c is a rEFInd filesystem driver file; however, I've also tested booting the kernel from the FAT32 ESP, and even with the rEFInd filesystem driver never loaded, and the kernel still fails to boot, so this is not a filesystem driver problem per se.) * Sometimes (usually when doing a cold boot), the kernel loads but then panics, as shown in boot-failure-2.png. Note that I've tried to boot this kernel in many ways -- via rEFInd, via the VirtualBox EFI shell; from the ext4fs root (/) filesystem via the rEFInd ext4fs driver, and from the FAT32 ESP; cold booting and warm booting. None of these approaches has worked, but the failure symptoms vary and are somewhat inconsistent, even when booting in exactly the same way -- sometimes the screen hangs with errors, other times that scrolling message about "CR has Bad Signature" appears; and error messages can vary randomly from one attempt to another. ** Attachment added: "Boot failure messages including rEFInd/UDK2014 debugging messages" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649326/+attachment/4826241/+files/boot-failure.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1649326 Title: EFI stub loader broken in kernel 3.13.0-101-generic (& later in 3.13 series) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649326/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
