our new Server with AMD EPYC and super micro board reboots ramdonly. There is no error message before the reboot in /var/log/messages. we are running 2 Server with VMWare workstation without any problem. The new server should run KVM. older servers with AMD (before EPYC) running KVM without any problem. any idea or recomme...

Good Evening, I recently purchased an EPYC quantum UPS. I installed NUT on the home assistant by connecting the UPS via USB and tried all the various drivers in the list, the only one that seems to work is: usbhid-ups with this log: s6-rc: info: service s6rc-oneshot-runner: starting s6-rc: info: service s6rc-oneshot-runner successfully sta...

> our new Server with AMD EPYC and super micro board reboots ramdonly. > There is no error message before the reboot in /var/log/messages. Anything in the hardware logs of the server like memory error or so? Any watchdog on the servers acting bad? We run CentOS 7 and KVM on AMD Opteron and AMD EPYC servers without issues. R...

...S 8 MarketPlace AMI 47k9ia2igxpcce2bzo8u3kj03 ( https://aws.amazon.com/marketplace/pp/prodview-ndxelprnnxecs) Now we have migrated these servers to CentOS Stream 8. We can change the instance type of these servers until m6i and c6i Intel based CPU, but we cannot change the instance type to new ADM Epyc c6a and m6a. There is an error triggered by the AWS console and saying to this marketplace server is not compatible with c6a and m6a instance types... Is there a reason for this situation (because this AMI is X86_64 compatible, so AMD Epyc should work with it) ? Do you know which team is managing t...

do we know if 7.4 is good for new AMD cpus? More specifically for virtualization. Historically there were some issues and things like AMD's IOMMU & similar were not exactly perfectly supported by HW vendors, UEFI/bios <=> kernel. I'm thinking of getting one and I wonder if it might be too soon. I wonder if above things are at least in an acceptable shape of older Opteron

What I meant is that POWER could become a competitor for Intel/AMD based servers. We're now running AMD EPYC servers with 64Cores/128Threads and we didn't find any POWER system which could compete in this area. Also, looking at TOP500 list there are not so many POWER systems anymore. IBM could change this now. Regards, Simon

Rented a new EPYC Rome Server from Hetzner, but sensors does not show status of all cores in list, which is why I asked. thanks. --- Lee

Will 5.0 have scheduler, reg alloc etc. bits for explicit support of AMD's 1st gen Zen (Ryzen, Epyc) arch? Is it safe to assume that the changes for Zen's 2nd gen will land prior to the hardware release, once the 1st gen is added? I think zen2 will arrive next year.

...this message in the logs: Mar 01 08:09:18 <hostname> pcp-pmie[2870]: Low random number entropy available 15.6%avail at beta.corp.invoca.ch This is on a 64 core "AMD Opteron(tm) Processor 6282 SE" server but I also got the same low entropy on an EL9 KVM guest running on a "AMD EPYC 7601" server. After a lot of searching the net I understand that rng has been reworked in 5.x kernels and /proc/sys/kernel/random/entropy_avail reaches only 256 in default configurations. But why does it go too low on a test system with almost not load? Is this an issue with AMD CPUs or does...

As a matter of interest, did you look at IBM's own Power Systems (IBM System i, AS/400, System p, as was)? They promote some of these models as having very powerful processing capabil...

Hi, all We use AMD Rome CPUs, like EPYC 7452. RHEL said that RHEL 7.6.6 began to support these cpus(detials: https://access.redhat.com/support/policy/amd) , but we found that CentOS7.6 with kernel 3.10.0-957.21.3.el7.x86_64 also works fine. So, my questions are: 1) Is there any place that i can find the cpu support info? 2) Dose the ker...
