It seems to me as if bootstrap lists RAM regions beyond addressable memory. I have a region that is being limited:
Limiting 'RAM' region [100000000, 43e5fffff] {33e600000} to [100000000, 10ea7c3ff] { ea7c400} due to 3024 MB limit
but in fact has to be dropped if I am not completely mistaken. When dropping regions above ~0UL, everything works fine.

When I enable pagefault tracing, the last one I see is a fault at address 0xffffffff on that instruction. The respective source code is in /pkg/cxx/lib/tl/include/list_alloc:L182. I assume dereferencing c in c->next is the problem?
Yes, seems so. Coming back to the memory map provided by the bootloader, is there maybe a difference between the machine that works and this one? Maybe you could also try to nail down where that possible -1 is written e.g. with some if's at the write locations.
