Kernel 7.0.2 Problem with relax-intel-rmrr

[DuDu371]

Hello!
I'm using proxmox for over 1 decade on my HP Microserver Gen8. This machine have a known problem with the iommu that it's broken. 3 or 4 years ago i found that the pve kernel have a patch to enable

relax-intel-rmrr

and it's working fine since.

Following all the vulnerabilities that have come out this days i update my server and i saw that a new 7.0.2 kernel was installed. With this kernel my machine have constant 100% wait-io and it's inoperable.
Have the patches on kernel 7.0 been removed?

HI,

you could pin the old kernel and report a bug (if before it was a native kernel without modifications).
Is the mentioned patch was from here?
Could you clarify what kernel was installed before?
Is it was custom kernel or just custom options in a standard one?
Could you share a system report, dmesg and journal output or at least specific errors?
Could you provide more details about hardware?
