Description
Is your feature request related to a problem? Please describe.
Folks,
I had a test preempt RT with a number of variations. There are several patches and code cleanup in 6.1 and up.
It makes sense to elevate RT because, right now, it is unusable.
My second request is that the build that you posted for the initial installation actually boot no RT kernel. I think it makes sense that initially, whether it is ISO kickstart or ova, actually boot to target the RT kernel.
Describe the solution you'd like
- Elevate kernel 6.1 specifically for RT
- Cross-check all NVME. I see a very strange issue 6.0 FS doesn't report an error. i.e syscall doesn't return -1 while
- Update iso/ova that boots from the beginning to RT kernel.

Research direction
Start by breaking the request into kernel 6.1 PREEMPT_RT support, NVMe behavior, and ISO/OVA boot selection. Review the existing kernel, ISO, and OVA build and boot paths, then reproduce the reported NVMe syscall behavior. Done means the requested RT kernel is supported and the initial installation artifacts boot it as specified, with the NVMe issue checked.
