drsparks68 Posted June 24, 2018 Share Posted June 24, 2018 I've been getting machine check events and am looking to troubleshoot the issue. I have mcelog installed through Nerd Tools, but when I run 'mcelog', I get the following error: "mcelog: ERROR: AMD Processor family 21: mcelog does not support this processor. Please use the edac_mce_amd module instead. CPU is unsupported" I've searched on how to install the edac_mce_amd module but haven't found any good instructions yet. Anyone know how to install it so I can troubleshoot my server issues? Many thanks Quote Link to comment
drsparks68 Posted July 2, 2018 Author Share Posted July 2, 2018 Anyone? I keep getting this message and Google doesn't seem to be any help whatsoever. Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the unRaid forums. The output of mcelog (if installed) has been logged Quote Link to comment
Squid Posted July 2, 2018 Share Posted July 2, 2018 I had @limetech @eschultz add that module a few versions of unRaid ago, as I noticed that mcelog wouldn't work on the AMD processor, but I don't believe that it worked correctly. I have since moved on to Intel chips. Quote Link to comment
killeriq Posted August 7, 2019 Share Posted August 7, 2019 (edited) getting same error msg, any progress since? Fix Common Problems: Error: Machine Check Events detected on your server Aug 7 22:08:16 unRAIDTower root: mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor. Please use the edac_mce_amd module instead. or where to get AMD module i dont find it in nerdpack thanks Edited August 7, 2019 by killeriq Quote Link to comment
drsparks68 Posted August 8, 2019 Author Share Posted August 8, 2019 It ended up being bad memory for me. Once I removed the bad stick the machine check events went away. Quote Link to comment

Lucky you I have the same error but swapping the memory didn't change anything. So there is no edac_mce_amd? Quote Link to comment
andrew207 Posted July 22, 2020 Share Posted July 22, 2020 (edited) Yeah I've just started getting this one too now. I ran memtest and got 2 full successful passes, not really sure what to do. :~# mcelog mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor.

EvilMilkshake Posted September 29, 2020 Share Posted September 29, 2020 Same. Also experiencing this. Quote Link to comment
Squid Posted September 29, 2020 Share Posted September 29, 2020 The message from mcelog isn't as bad as it seems. The edac_mce_amd module has been included in Unraid for a while now. Effectively what the message means is that mcelog is telling you that that Intel driver doesn't work with your processor. The AMD driver is getting used instead. (At least that's what my googling found a week or 2 ago) Quote Link to comment

I see that the module is included root@unraid:~# lsmod | grep mce edac_mce_amd 32768 0 Does this mean we don't need to manually run anything and just provide our diag file? Quote Link to comment
Squid Posted December 2, 2020 Share Posted December 2, 2020 Yeah, it's a weird warning from mce that really means that it's not using the intel module Quote Link to comment

So those of us with AMD can ignore this error? Sent from my iPhone using Tapatalk Edited December 2, 2020 by MrLinux Quote Link to comment
Resviole Posted December 16, 2020 Share Posted December 16, 2020 Similar error for me, except for AMD Processor family 25 (5600x). Fix Common Problems alerts on it because of the message added to mcelog. Can we safely ignore this error as AMD users? Full message: "mcelog: ERROR: AMD Processor family 25: mcelog does not support this processor. Please use the edac_mce_amd module instead." Quote Link to comment

It will alert on an MCE being logged (which is the only time that message arrives). If the mce happens during processor initialization, then it's nothing at all to worry about as that affects certain combinations of hardware from time to time. Quote Link to comment
ruihere Posted June 25, 2022 Share Posted June 25, 2022 @Squid I am AMD 5600U, and I got the same message: Jun 22 11:44:34 server mcelog: ERROR: AMD Processor family 25: mcelog does not support this processor. Please use the edac_mce_amd module instead. and I noticed that since I switched to AMD, my mac VM won't work anymore. I got this from my VM log: 2022-06-25T17:05:38.958203Z qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.01H:ECX.pcid [bit 17] 2022-06-25T17:05:38.958268Z qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.fma4 [bit 16] 2022-06-25T17:05:38.959351Z qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.01H:ECX.pcid [bit 17] 2022-06-25T17:05:38.959365Z qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.fma4 [bit 16] are they related ? thanks Quote Link to comment
Squid Posted June 25, 2022 Share Posted June 25, 2022 The mce error is more or less a very badly worded message saying that the default driver doesn't work and that edac is being used instead. For the VM issue, you'd want to create a new thread, and include your diagnostics as it's not particularly relevant to this thread. Quote Link to comment
John_M Posted June 28, 2022 Share Posted June 28, 2022 On 6/25/2022 at 6:24 PM, ruihere said: my mac VM won't work anymore MacOS expects very specific capabilities of the CPU and several of them have to be faked in the XML. In particular, it expects to see "GenuineIntel" as the vendor string and not "AuthenticAMD". You don't say how you first created your VM but I recommend you take a look at the MacInABox Docker container help pages for more information. SpaceInvaderOne, the author, has also created a video showing how to use it. The purpose of that container is to create a macOS VM - you run it once and then rarely need it again. Your best solution might be to create a new VM using that method, install a fresh copy of macOS, then import your data, either from your original virtual HD image or from a Time Machine backup. Alternatively, if you're comfortable editing your XML manually you could do that. The parts that describe the CPU are in the <qemu: commandline> block at the end of the file, after the <devices> section. Here are the last twelve lines of an XML file that works for me, created using the MacInABox container. <qemu:commandline> <qemu:arg value='-usb'/> <qemu:arg value='-device'/> <qemu:arg value='usb-kbd,bus=usb-bus.0'/> <qemu:arg value='-device'/> <qemu:arg value='isa-applesmc,osk=REDACTED'/> <qemu:arg value='-smbios'/> <qemu:arg value='type=2'/> <qemu:arg value='-cpu'/> <qemu:arg value='Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+aes,+xsave,+xsaveopt,check'/> </qemu:commandline> </domain> Quote Link to comment
Revan335 Posted September 23, 2023 Share Posted September 23, 2023 (edited) Same on AMD Ryzen 7 PRO 5750G. Maybe this was helpful for all and more clearly. Edited September 23, 2023 by Revan335 1 Quote Link to comment
