Sorry to join the bandwagon late this time, but i got these errors while booting:
[ 0.826901] ACPI BIOS Error (bug): Could not resolve [\_SB.PCI0.GPP2.WWAN], AE_NOT_FOUND (20180810/dswload2-160) [ 0.826908] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20180810/psobject-221) [ 0.826910] ACPI Error: Ignore error and continue table load (20180810/psobject-604) [ 0.826912] ACPI Error: Skip parsing opcode OpcodeName unavailable (20180810/psloop-543) [ 0.827236] ACPI BIOS Error (bug): Could not resolve [\_SB.PCI0.GPP2.WWAN], AE_NOT_FOUND (20180810/dswload2-160) [ 0.827239] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20180810/psobject-221) [ 0.827241] ACPI Error: Ignore error and continue table load (20180810/psobject-604) [ 0.827242] ACPI Error: Skip parsing opcode OpcodeName unavailable (20180810/psloop-543) [ 0.827245] ACPI BIOS Error (bug): Failure creating [\_SB.PCI0.GPP5.EWPM], AE_ALREADY_EXISTS (20180810/dswload2-316) [ 0.827248] ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20180810/psobject-221) [ 0.827250] ACPI BIOS Error (bug): Failure creating [\_SB.PCI0.GPP5._PRW], AE_ALREADY_EXISTS (20180810/dswload2-316) [ 0.827252] ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20180810/psobject-221) [ 0.827254] ACPI Error: Skip parsing opcode OpcodeName unavailable (20180810/psloop-543) [ 0.827257] ACPI BIOS Error (bug): Failure creating [\_SB.PCI0.GPP5.RTL8._S0W], AE_ALREADY_EXISTS (20180810/dswload2-316) [ 0.827259] ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20180810/psobject-221)I think this is after the new update
Processor : AMD Ryzen 7 7840HS

Hi,
It's just an ACPI error, it shouldn't be a problem.
-
I agree. But just thought I should report nevertheless.
Update: This seems to be related to 7840HS motherboard. I tried it on another AMD Ryzen 7945HX but did not get this error.
-
It's clearly due to the motherboard, yes. Mostly buggy BIOS/UEFI and ACPI tables. This world is like the far west.

New security and maintenance update candidate
A new XSA (Xen Security Advisory) was published on the 8th of July, related to hardware vulnerabilities in several AMD CPUS. Updated microcode mitigate it, and Xen is updated to adapt to the changes in the CPU features. We also publish other non-urgent updates which we had in the pipe for the next update release.
Security updates
amd-microcode:- Update to 20250626-1 as redistributed by XenServer.
xen-*:- Fix XSA-471 - New speculative side-channel attacks have been discovered, affecting systems running all versions of Xen and AMD Fam19h CPUs (Zen3/4 microarchitectures). An attacker could infer data from other contexts. There are no current mitigations, but AMD is producing microcode to address the issue, and patches for Xen are available. These attacks, named Transitive Scheduler Attacks (TSA) by AMD, include CVE-2024-36350 (TSA-SQ) and CVE-2024-36357 (TSA-L1).
Maintenance updates
http-nbd-transfer:- Fix missing import exceptions in log files.
- Fix a potential HA startup failure with LINSTOR.
xo-lite: update to 0.12.1- [Charts] Fix tooltip overflow when too close to the edge
- [Host/VM/Dashboard] Fix timestamp on some charts
Test on XCP-ng 8.3
yum clean metadata --enablerepo=xcp-ng-testing yum update --enablerepo=xcp-ng-testing rebootThe usual update rules apply: pool coordinator first, etc.
Versions:
amd-microcode: 20250626-1.1.xcpng8.3http-nbd-transfer: 1.7.0-1.xcpng8.3xen: 4.17.5-15.1.xcpng8.3xo-lite: 0.12.1-1.xcpng8.3
What to test
Normal use and anything else you want to test.
Test window before official release of the updates
~2 days.

S stormi forked this topic
-
And fixes for XCP-ng 8.2 are coming but they require more work to backport the patches.
-
Tested on my usual Intel test servers you've seen me post in this thread in the past as well as a 2 host AMD Epyc pool,(HP DL325 Gen10) rolling pool reboot worked as expected, hosts rebooted without issue, backups and replication appear to function as usual.
-
@gduperrey Installed and running on Intel systems, and Zen3 system that sees the microcode update.
-
Installed fine. Didn't get a chance to deep dive and/or test features.

One of the configured repositories failed (XCP-ng Updates Repository), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=xcp-ng-updates ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable xcp-ng-updates or subscription-manager repos --disable=xcp-ng-updates 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=xcp-ng-updates.skip_if_unavailable=true failure: repodata/0a94f9d57be162987a7e5162b4471809af2ee0897e97cc24187077fb58804380-primary.sqlite.bz2 from xcp-ng-updates: [Errno 256] No more mirrors to try. http://mirrors.xcp-ng.org/8/8.3/updates/x86_64/repodata/0a94f9d57be162987a7e5162b4471809af2ee0897e97cc24187077fb58804380-primary.sqlite.bz2: [Errno 14] HTTPS Error 404 - Not FoundPerhaps mirrors are still syncing?
-
@flakpyro Yes, it always takes a little time for the mirrors to synchronize.
I'm getting correct feedback from the main repository (https://updates.xcp-ng.org/) with the correct updates available.
-
@gduperrey I wonder why now I have to run those commands on my hosts each time for the updates to show:
yum clean all rm -rf /var/cache/yumNot fun
-
Uggg... Just after I upgraded 8.2.1 to 8.3.x and did updates. Guess I have more waiting for me for later today or tomorrow.
-
@flakpyro
I'm good now! -
Updated around 43 hosts without issue.
-
I'm doing the latest production level updates announced yesterday... My pool has never migrated VMs as fast as it is now.
That was migrating several at a time, moving VMs back to "balanced" at the end is moving them at about half that speed one at a time. This is more than double what I was able to do with the same hardware on 8.2.1. It looks like it is actually capping at the maximum 10gbps speeds that the x710 cards and my switch can handle, that's never happened, not even on my lab which has been on v8.3 for over a year.
(note to self, might be time to upgrade those x520 cards in the lab to x710)
Next month's Windows updates might be interesting, hope this increase holds for that process too.
