I tried to debug another problem and turned on most debug options for memory.
The resulting kernel failed to boot.
Bisecting the configurations led to CONFIG_DEBUG_VIRTUAL - if I turned it on
in addition to some other debug options, the machine crashed with
kernel BUG at arch/x86/mm/physaddr.c:79!
Screenshot at http://kodu.ut.ee/~mroos/debug_virtual-boot-hang-1.jpg
The machine was Athlon XP with VIA KT600 chipset and 2G RAM.

Does this still happen on 5.1-rc2?
Do you have idea as to what max_low_pfn() gets set to on your system at boot time?
From the screen shot I'm guessing it MIGHT be 0x373fe, but it's hard to know for sure.

Yes. 4.20 and 5.0 and anything after that up to 5.1-rc2.

The dmesg output you posted confirms that max_low_pfn is indeed 0x373fe, and it appears
that the value of phys_mem being checked mat be 0x3f401ff1, which translates to pfn 0x3f401,
at least if what's still in registers can be believed.
Since that is indeed greater than max_low_pfn, VIRTUAL_BUG_ON triggers:
VIRTUAL_BUG_ON((phys_addr >> PAGE_SHIFT) > max_low_pfn);
Looking at the call stack of
copy_strings_0x220
__check_object_size+0xef
that looks to translate to this sequence:
copy_from_user(kaddr+offset, str, bytes_to_copy)
check_copy_size(kaddr+offset, bytes_to_copy, FALSE)
check_object_size(kaddr+offset, bytes_to_copy, FALSE)
__check_object_size(kaddr+offset, bytes_to_copy, FALSE)
check_heap_object(kaddr+offset, bytes_to_copy, FALSE)
virt_to_head_page(kaddr+offset)
virt_to_page(kaddr+offset)
pfn_to_page(kaddr+offset)
__pa(kaddr+offset)
__phys_addr(kaddr+offset)
so it appears the address is "too high" for low memory at that point.
