I have tested with the following patches reverted:

                [PATCH 6.1 43/71] x86/mmio: Disable KVM mitigation when X86_FEATURE_CLEAR_CPU_BUF is set
                [PATCH 6.1 44/71] Documentation/hw-vuln: Add documentation for RFDS
                [PATCH 6.1 45/71] x86/rfds: Mitigate Register File Data Sampling (RFDS)
                [PATCH 6.1 46/71] KVM/x86: Export RFDS_NO and RFDS_CLEAR to guests

and the kernel still doesn't boot.

I have realized that in Kconfig, I have CONFIG_DEBUG_PREEMPT enabled for some weird reason.
I alsa have CONFIG_EARLY_PRINTK_USB_XDBC=y, which may cause error messages not to
appear on screen (according to Kconfig description). Will test with both options disabled.

Greetings,

Mateusz
