B25941 - booting ISO fails with STOP UNSUPPORTED_PROCESSOR - SOLVED
- The issue has been solved in b25987 (or earlier). This could be due to code changes. It could be also the case that now, after the official release of Intel's 14th gen CPUs, the microcode, formerly implemented by ISV as "Intel next gen" is now accepted by the kernel.
Either way, thank you very much!
So it is clear now about the cause.
The IPU from WS 2022 to vNext fails with the same error as baremetal installation, initially reported.
BSOD UNSUPPORTED_PROCESSOR
Reading the article from Günter (ex MVP) and xeno I believe MSFT should dig into this instead of tinkering from Insiders.
SetupDiag: processing rule: FindRollbackFailure.

The error in setupdiag is misleading. The BSOD occours right after the first reboot attempt of the IPU sequence, so when loading the kernel
Wished we would have feedback hub app in Windows Server, that would make all our lives easier for sake of logging. There are no dmp files available.

Dear Server Insider Team,
It's a bit disappointing there has been no feedback on this matter.
I believe to have found the root cause for this issue.
The issue has been confirmed by Microsoft, according to several blogposts, but only for Windows 11 Insider Client OS.
The underlying issue seems to emerge on Intel 600 and 700 series chipsets, which lately received (or made available) a new UEFI update to support unreleased Intel 14th gen CPUs (named next gen CPUs, in release notes) on these platforms.
Installed the latest UEFI not looking for this support, rather as best practice.
MSI has worked on a fix with Microsoft and re-released their next gen CPU update support. Other vendors seem pending here.
I strongly believe this is the cause of my trouble reading the articles around it and the changelog from MSI.
If anyone else reading this has a sophisticated setup and has installed the UEFI Update, and is now affected contact your Mainboard vendor support/ OEM and pointing to the next gen CPU support as a possible reason.
