Bug 714178 – sys-kernel/gentoo-sources-5.4.26+: undefined reference to `efi_mem_type'

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Kim B. Sindalsen 2020-03-24 14:28:48 UTC]

Kernel 5.4.26 (and 27) threw the following link failure:

  CC      drivers/usb/storage/option_ms.o

Seems like https://bugs.gentoo.org/713460 (for gentoo-sources-5.5.9)

Reproducible: Always

Triggered by this kernel-config (which has been used via make oldconfig for my older 5.4-series).

please *attach* all files. Logs and .config. Do not use pastebins.
Reopen the ticket afterwards.

Created attachment 625294 [details]
kernel config

My 5.4.25-config triggering the issue at 5.4.26 and 5.4.27

[Comment 4 Mike Pagano 2020-03-24 17:12:18 UTC]

Please reest with CONFIG_EFI set

[Comment 5 Kim B. Sindalsen 2020-03-24 18:13:27 UTC]

Do you mean editing .config and set CONFIG_EFI=n ?

That works.

Also building with upstream-patch from bug 713460 - https://bugs.gentoo.org/713460 works with CONFIG_EFI unset.

System is a non-EFI system.

Also trying CONFIG_EFI=y now - builds, though not sure of impact.

[Comment 6 Mike Pagano 2020-03-24 18:57:38 UTC]

Ok, that's actually our patch, not upstream. I can include in in the next gentoo-sources 5.4

[Comment 7 Mike Pagano 2020-04-04 22:33:00 UTC]

This patch is in the kernel series >= 5.4.29
