Bug 81891

Correction, after bisecting it turns out that it actually is the recent x86-efi-for-linus branch merge that causes the laptop to fail to boot:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=76f09aa464a1913efd596dd0edbf88f932fde08c

Attached is a picture of the message it prints.

In case it matters, laptop is a Clevo W840SU, mobo of the desktop a Gigabyte G1.Sniper M5 (bios F9a).

boot failure

Andreas, it would be helpful if you could track down exactly which commit introduces this regression.

The commit that introduced the "setup_efi_pci() failed" message is this one, but I doubt that it's directly responsible for your issues,

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/x86/boot/compressed/eboot.c?id=fb86b2440de0ec10fe0272eb19d262ae7a01adb8

Alright, the commit that causes my laptop to fail is "x86/efi: Support initrd loaded above 4G", checked both by bisection and reverting it from the current HEAD.

https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?h=x86-efi-for-linus&id=4bf7111f50167133a71c23530ca852a41355e739

Still getting the "setup_efi_pci() failed!".

Laptop has 8G RAM and the desktop 16G. Also, the laptop uses dm-crypt drive encryption.

Andreas, thanks for doing the bisect. Could you please provide dmesgs for both of your machine with a working kernel?

Also, please let me know if the following commit helps (you'll need to add efi=nochunk to your EFI boot stub params),

dmesg

Yes, the commit together with efi=nochunk works (kernel at 899552d6). Attached is the resulting dmesg.

dmesg desktop

Ups, forgot about the second dmesg. Here it is.

I pulled from linus' repo yesterday (commit 899552d6e84babd24611fd36ac7051068cb1eb2d) and received this same error message when trying to boot into the kernel.  I was not actually able to boot into the kernel due to kernel panic about not being able to mount the root fs (I'm a newb so am not sure if this is relevant to the specified error).  I did not know how to obtain log data from the boot, so I attached a picture of the kernel panic core dump.  Sorry I am not more help!

kernel panic core dump after "setup_efi_pci() failed"

I should note that it says to 'Please append a correct "root=" boot option', but I do have this kernel parameter set (to root=/dev/sda3).

Jaret, could you try building a kernel with the following patch?

http://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit/?h=urgent&id=47226ad4f4cfd1e91ded7f2ec42f83ff1c624663

Hopefully that should fix your boot failure.

Can't speak for Jaret, but it's working for my laptop, unsurprisingly.

Gah, I feel like a jerk.  I have actually re-installed Windows on my PC in order to practice .NET programming (I am currently not a programmer but trying to find a programming position).  Odds are I will switch back to Linux in the near future, but I won't be able to test out this patch for a little while.  Thank you so much for responding to my post though. =/

with that patch my computer boots however showing the "setup_efi_pci() failed" message. without it i get something mentioning initramfs containing junk and stops there.

this is on a desktop with the motherboard MSI Z77A-G45 Socket-1155, with kernel 3.17-rc5

When running on x86_64 3.17-rc6 compiled from git, my Asus laptop displays "setup_efi_pci() failed" and then immediately reboots. The system boots fine on 3.16. I'll attach dmesg from booting into 3.16. There's no additional debug data displayed. It looks like 3.17-rc6 contains Matt's patch. I'll try and figure out what the last 3.17 rc I can boot into is and bisect, but if there's anything additional I can do to assist debugging please let me know.

Maybe try with the revert contained in rc7:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f3670394c29ff3730638762c1760fd2f624e6d7b

Sounds like the same issue.

Rebuilt on the latest and it works. Still displays the setup_pci_efi error, but it continues to boot. Thanks.

Given the fixes for both the boot failures and the "failed" message (with "x86/efi: Delete misleading efi_printk() error message" in rc7), I'll take the liberty of closing the bug. Thanks, devs!
