Yes, my test was with that exact kernel. Earlier today I installed 3.9.4-saucy. And the problem still exists. Here are my steps.
1. I use rEFInd, not GRUB, to boot. I made a copy of the rEFInd boot loader, just to be sure that efibootmgr isn't throwing the error in case you're trying to create a second NVRAM variable that duplicates an existing one. cp /boot/efi/EFI/refind/refind_x64.efi /boot/efi/EFI/refind/Zrefind_x64.efi 2. Add a new NVRAM variable. On my ThinkPad T520, the EFI system partition is /dev/sda1. efibootmgr -c -d /dev/sda -p 1 -l '\EFI\refind\Zrefind_x64.efi' -L 'Z rEFInd Boot Manager' 3. Observe the following entry while tailing /var/log/syslog: May 31 10:18:50 t520 kernel: [ 2245.867115] efivars: set_variable() failed: status=8000000000000009 4. Double-check the NVRAM contents. As you can see, I have only the one entry for the original rEFInd boot loader. Attempting to add the "Zrefind_x64.efi" loader indeed failed. root@t520:~# efibootmgr -v BootCurrent: 0019 Timeout: 0 seconds BootOrder: 0019,0006,000C,0007,000A,0008,000D,000E,000F,000B,0009,0011,0012,0010,0013 Boot0000 Setup Boot0001 Boot Menu Boot0002 Diagnostic Splash Screen Boot0003 Startup Interrupt Menu Boot0004 ME Configuration Menu Boot0005 Rescue and Recovery Boot0006* USB CD 030a2400d23878bc820f604d8316c068ee79d25b86701296aa5a7848b66cd49dd3ba6a55 Boot0007* USB FDD 030a2400d23878bc820f604d8316c068ee79d25b6ff015a28830b543a8b8641009461e49 Boot0008* ATAPI CD0 030a2500d23878bc820f604d8316c068ee79d25baea2090adfde214e8b3a5e471856a35401 Boot0009 ATA HDD2 030a2500d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f602 Boot000A* ATA HDD0 030a2500d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f600 Boot000B ATA HDD1 030a2500d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f601 Boot000C* USB HDD 030a2400d23878bc820f604d8316c068ee79d25b33e821aaaf33bc4789bd419f88c50803 Boot000D* PCI LAN 030a2400d23878bc820f604d8316c068ee79d25b78a84aaf2b2afc4ea79cf5cc8f3d3803 Boot000E ATAPI CD1 030a2500d23878bc820f604d8316c068ee79d25baea2090adfde214e8b3a5e471856a35403 Boot000F ATAPI CD2 030a2500d23878bc820f604d8316c068ee79d25baea2090adfde214e8b3a5e471856a35404 Boot0010 Other CD 030a2500d23878bc820f604d8316c068ee79d25baea2090adfde214e8b3a5e471856a35406 Boot0011 ATA HDD3 030a2500d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f603 Boot0012 ATA HDD4 030a2500d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f604 Boot0013 Other HDD 030a2500d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f606 Boot0014* IDER BOOT CDROM ACPI(a0341d0,0)PCI(16,2)ATAPI(0,1,0) Boot0015* IDER BOOT Floppy ACPI(a0341d0,0)PCI(16,2)ATAPI(0,0,0) Boot0016* ATA HDD 030a2400d23878bc820f604d8316c068ee79d25b91af625956449f41a7b91f4f892ab0f6 Boot0017* ATAPI CD: 030a2400d23878bc820f604d8316c068ee79d25baea2090adfde214e8b3a5e471856a354 Boot0018* PCI LAN 030a2400d23878bc820f604d8316c068ee79d25b78a84aaf2b2afc4ea79cf5cc8f3d3803 Boot0019* rEFInd Boot Manager HD(1,28,100000,35a3de7a-7015-4855-b882-1c8e9432b8fe)File(\EFI\refind\refind_x64.efi) Maybe something changed between that first 3.9-saucy build and the newer 3.9.3 and 3.9.4 builds? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1173423 Title: Kernel fails to update EFI vars, rendering system unbootable [P8P67 PRO REV 3.1, BIOS 1904 08/15/2011] To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1173423/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
