http://bugzilla.opensuse.org/show_bug.cgi?id=1192288 Bug ID: 1192288 Summary: amd64_edac_mod does not load after CPU upgrade Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.3 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: seroton10@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- On a server running an AMD Ryzen 9 3900X CPU, I use the following output, written during boot, to verify that DRAM ECC is enabled: Oct 31 13:44:48 blackbox kernel: EDAC MC: Ver: 3.0.0 ...

(No other hardware or software changes were made.) Now I only see the first line mentioning EDAC in the log: Nov 02 13:28:54 blackbox kernel: EDAC amd64: F19h detected (node 0). Nov 02 13:28:54 blackbox kernel: EDAC amd64: Error: F0 not found, device 0x1650 (broken BIOS?) An attempt to manually load the AMD EDAC driver fails: # modprobe amd64_edac_mod modprobe: ERROR: could not insert 'amd64_edac_mod': No such device Would it be possible to add or backport the missing hardware support in the Leap 15.3 kernel, please? -- You are receiving this mail because: You are on the CC list for the bug.
