dmesg output
output of lspci -vvv dmesg output before inserting efivars module Abort GetNextVariableName() if we start seeing duplicate entries dmesg output with patch applied dmesg output after removing the "Boot-0 !..."-entry dmesg |
||
This is on a HP EliteBook 8530w. The problem first occurred after trying to add a boot entry with efibootmgr, which first displayed an error and hung after a second try. (Sorry - I can't give any details on how to reproduce this since it depends on efivars) Also Microsofts bcdedit tool can't cope with this and hangs - this results in windows not being bootable and not being (re-)installable (mentioning that only to give more details on the symptoms - this is of course a problem between me and M$).
Also the efishell shows only a cursor for a while and afterwards restarts. Writing a new BIOS/UEFI-firmware from HP doesn't fix this, as for changing the boot order in the BIOS/UEFI-setup. (HP refers to it as BIOS firmware/setup)
Some details on my installation:

dmesg output before inserting efivars module
I just saw that this info was missing in the other dmesg output.
Unfortunately I suspect that the implementation of GetNextVariableName() in your firmware is broken (likely) or efibootmgr failed at a bad time and did something funky with your variable store (unlikely), which is why you're seeing the efivars code loop.
If possible, I'd try go into the BIOS menu on startup and see if you can delete the boot entry that you added. Otherwise, if you've got the 'setvar' command available to you at the UEFI shell you might want to try something like,
'setvar <BOOT VARIABLE NAME> data='
which should delete the variable.
I've actually got a HP EliteBook here so I'll try and recreate this bug. If it is a bug in the firmware then we'll probably have to add some kind of a workaround to efivars.
UEFI shell fails to start - it just displays a white cursor on a black screen not responding to any input. (The EDK2 version does not support my hardware I think) I also can't see any way to set the entry in the BIOS menu - only hardware boot order, but not the UEFI entries... Maybe there is a way to just completely wipe all the entries and then recreate the ones I need? Created attachment 81531 [details]
Abort GetNextVariableName() if we start seeing duplicate entries
This patch should at least get your kernel booting again. I'd then attempt to delete the Boot00* variables from /sys/firmware/efi/vars/ if possible.
I suspect the first entry is the problem: Boot-0 !8be4df61-93ca-11d2-aa0d-00e098032b8c/ Boot0005-8be4df61-93ca-11d2-aa0d-00e098032b8c/ Boot0006-8be4df61-93ca-11d2-aa0d-00e098032b8c/ Boot0007-8be4df61-93ca-11d2-aa0d-00e098032b8c/ Boot0008-8be4df61-93ca-11d2-aa0d-00e098032b8c/ cat /sys/firmware/efi/vars/Boot-0\ \!8be4df61-93ca-11d2-aa0d-00e098032b8c/* EFI_VARIABLE_NON_VOLATILE EFI_VARIABLE_BOOTSERVICE_ACCESS EFI_VARIABLE_RUNTIME_ACCESS 8be4df61-93ca-11d2-aa0d-00e098032b8c ��+� !a���ʓ�� 0xa cat /sys/firmware/efi/vars/Boot0005-8be4df61-93ca-11d2-aa0d-00e098032b8c/* EFI_VARIABLE_NON_VOLATILE EFI_VARIABLE_BOOTSERVICE_ACCESS EFI_VARIABLE_RUNTIME_ACCESS Notebook Upgrade Bay �8be4df61-93ca-11d2-aa0d-00e098032b8c Notebook Upgrade Bay �0x84 How can I delete the entry? You should be able to use efibootmgr to delete entries. Something like, efibootmgr -B -b <bootnum> Created attachment 82041 [details]
dmesg output with patch applied
But efibootmgr doesn't list the faulty first entry. # efibootmgr Boot0005* Notebook Upgrade Bay Boot0006* Windows Boot Manager Boot0007* Gentoo Linux A Boot0008* ubuntu So how do I delete the "Boot-0 !8be4df61-93ca-11d2-aa0d-00e098032b8c/" entry, which causes the trouble? I've deleted the other entries, but still no way to fix the problem... Which entries have you deleted? Do you still need a way to delete the Boot-0 entry? If so you could try out the new efivarfs file system that is available on the 'next' branch here, git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git mount it with: mount -t efivarfs none /sys/firmware/efi/efivars and use rm to delete /sys/firmware/efi/efivars/Boot-0* (In reply to comment #14) > Which entries have you deleted? The ones I was able to: Boot0005 to Boot0008 > mount it with: mount -t efivarfs none /sys/firmware/efi/efivars > and use rm to delete /sys/firmware/efi/efivars/Boot-0* After I applied the "Abort GetNextVariableName() if we start seeing duplicate entries"-patch, I was able to delete the "Boot-0 ..." entry. Now I'm up and running again. Thx! That's good news. Thanks for your persistence. Am I correct in thinking that you have no Boot* variables now? Presumably you also no longer see any messages in dmesg about duplicate EFI variables? Could you try using efibootmgr to install a boot variable again and see what happens? I'm trying to work out whether the patch in this thread needs to go to mainline or whether it was just a freak accident that caused the bogus entry to be created. After deleting the last Boot* entry and rebooting the default entries were recreated, those are: Boot0000* Notebook Hard Drive Boot0001* Notebook Upgrade Bay Boot0002* Notebook Ethernet Boot0003* USB Hard Drive Boot0004* USB Hard Drive Boot0005* SD Card And I was also able to install a new boot entry with efibootmgr (this was on an unpatched 3.6.2-kernel): # efibootmgr BootCurrent: 0006 Timeout: 0 seconds BootOrder: 0006,0001,0004,0000 Boot0000* Notebook Hard Drive Boot0001* Notebook Upgrade Bay Boot0002* Notebook Ethernet Boot0003* USB Hard Drive Boot0004* USB Hard Drive Boot0005* SD Card Boot0006* gentoo But although the "Boot-0 !..." has respawned, it seems to cause no problems with an unpatched kernel: # ls /sys/firmware/efi/vars/ ADMIN_POLICY-6fb5dfea-69cf-429e-b78f-8fa59bb41d5e AcpiGlobalVariable-af9ffd67-ec10-488a-9dfc-6cbf5ee22c2e AutoDriveLockSecData-05299c28-3941-4c22-386b-7516e5666f8b BIOSAdminScanCode-29c59d66-f2b4-435e-9a75-e5e6e4973c22 BiosUser00-29c59d66-f2b4-435e-9a75-e5e6e4973c22 BiosUser01-29c59d66-f2b4-435e-9a75-e5e6e4973c22 BiosUser02-29c59d66-f2b4-435e-9a75-e5e6e4973c22 BiosUser03-29c59d66-f2b4-435e-9a75-e5e6e4973c22 BiosUser04-29c59d66-f2b4-435e-9a75-e5e6e4973c22 Boot-0 !8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0000-8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0001-8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0002-8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0003-8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0004-8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0005-8be4df61-93ca-11d2-aa0d-00e098032b8c Boot0006-8be4df61-93ca-11d2-aa0d-00e098032b8c BootCurrent-8be4df61-93ca-11d2-aa0d-00e098032b8c BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c ConIn-8be4df61-93ca-11d2-aa0d-00e098032b8c ConInDev-8be4df61-93ca-11d2-aa0d-00e098032b8c ConOut-8be4df61-93ca-11d2-aa0d-00e098032b8c ConOutDev-8be4df61-93ca-11d2-aa0d-00e098032b8c ConsoleLock-368cda0d-cf31-4b9b-8cf6-e7d1bfff157e ErrOutDev-8be4df61-93ca-11d2-aa0d-00e098032b8c KbcVersion-8be4df61-93ca-11d2-aa0d-00e098032b8c Lang-8be4df61-93ca-11d2-aa0d-00e098032b8c LangCodes-8be4df61-93ca-11d2-aa0d-00e098032b8c MTC-eb704011-1402-11d3-8e77-00a0c969723b MeBiosExtensionSetup-1bad711c-d451-4241-b1f3-8537812e0c70 PwRecData00-29c59d66-f2b4-435e-9a75-e5e6e4973c22 PwRecData01-29c59d66-f2b4-435e-9a75-e5e6e4973c22 PwRecData02-29c59d66-f2b4-435e-9a75-e5e6e4973c22 PwRecData03-29c59d66-f2b4-435e-9a75-e5e6e4973c22 PwRecData04-29c59d66-f2b4-435e-9a75-e5e6e4973c22 QuickLookBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c SYSTEM_POLICY_NAME-6fb5dfea-69cf-429e-b78f-8fa59bb41d5e SmmS3NvsData-8983fd2d-113c-4e2b-8f47-0abfeb20a41a TempBIOSAdminScancode-29c59d66-f2b4-435e-9a75-e5e6e4973c22 Timeout-8be4df61-93ca-11d2-aa0d-00e098032b8c USER_POLICY-6fb5dfea-69cf-429e-b78f-8fa59bb41d5e VPROState-a82471a8-e491-42c1-9240-4fde3073c0fd del_var dump-type0-1-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-10-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-11-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-2-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-3-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-4-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-5-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-6-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-7-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-8-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 dump-type0-9-1336463270-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0 mAsfBootOptionsNVRAM-c2a2fb8a-cf40-4cfd-b9e6-146a3cf758b2 new_var SO I would vote for freak...
