Ubuntu server:
Description: Ubuntu 19.10
Release: 19.10
Installed kernel:
linux-generic:
Installed: 5.3.0.42.36
(I could not figure out what package to select in the 'in what package did you find this bug' chooser)
Expected behavior: ECC RAM is detected and utilized
Result instead:
Error in dmesg at boot:
EDAC amd64: Error: F0 not found, device 0x1460 (broken BIOS?) (more in the attached KernelErrors.log)
Kernel 5.3 is missing ECC support for some families of AMD Ryzen 3rd gen CPUs.
Support is added via these two commits in the mainline tree:
https://github.com/torvalds/linux/commit/e53a3b267fb0a79db9ca1f1e08b97889b22013e6
https://github.com/torvalds/linux/commit/3e443eb353eda6f4b4796e07f2599683fa752f1d
The second commit actually adds the missing support, but it relies on the first commit: a partial refactor of the AMD ECC code.
I tested myself, followed the instructions at https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel to build my own kernel, cherry-picked the two above commits, and have working ECC support on my self-built kernel:
Linux smaug 5.3.0-43-generic #36 SMP Sat Mar 21 02:33:30 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux:
EDAC MC: Ver: 3.0.0

EDAC PCI0: Giving out device to module amd64_edac controller EDAC PCI controller: DEV 0000:00:18.0 (POLLED)
AMD64 EDAC driver v3.5.0
If this could be included in a future hardware support kernel release, that would be very helpful. I am unsure what the policy is for including this kind of backport in non-LTS kernels, though I know the LTS releases have hardware support updates that include this type of fix. |
