On 6.12-rc1, the kernel doesn't init properly:

It's not obvious to me what the issue could be, will have to spelunk the kernel source. Disabling the mainline CI job for now.

Weird! Maybe this is an rc1 regression?

It is. https://github.com/torvalds/linux/commit/ee4cdf7ba857a894ad1650d6ab77669cbbfa329e broke v6.12-RC1. It will be fixed in RC2 https://lore.kernel.org/all/cbaf141ba6c0e2e209717d02746584072844841a.1727722269.git.osandov@fb.com/

So I think we can close this issue, as its not a vimto bug but a p9 bug
