Thanks, the change to a larger single page makes sense. I assume we
would still be susceptible to a #GP once the kernel steps into it?

Since this is addressing acute crashes on L1VH, it would be good to
merge a fix first IMO. it can then be easily cherrypicked into
backports or distro-kernels.

Or would you rather see the problem addressed as part of in your
deposit-pages refactoring?

best,
