Since i upgraded from Qemu 9.0.2-1 to 9.1.0-2 i'm getting on all Linux guests these kind of error messages:
Sep 12 15:55:53 debian-webserver kernel: mce: [Firmware Bug]: Your BIOS is not setting up LVT offset 0x2 for deferred error IRQs correctly.
Sep 12 15:55:53 debian-webserver kernel: [Firmware Bug]: cpu 0, try to use APIC520 (LVT offset 2) for vector 0xf4, but the register is already in use for vector 0x0 on this cpu

All virtual machines running fine so far to be honest. After a downgrade to preveous version 9.0.2-1 all error messages disapear.
Before i start to do something i like to ask whether anyone else has the same experiences ?

i386: Add support for SUCCOR feature
Add cpuid bit definition for the SUCCOR feature. This cpuid bit is required to
be exposed to guests to allow them to handle machine check exceptions on AMD
hosts.
----
v2:
- Add "succor" feature word.
- Add case to kvm_arch_get_supported_cpuid for the SUCCOR feature.

Great job man! Thank you very much for your efforts. :-)
More or less perfectly and i saved a lot of time for searching the rights commits. I would have done the same steps.
I have already commented on the ticket.
