Sometimes SystemServer will crash on startup, sometimes it will softlock after mounting the root, maybe SyncTask will crash with:
[SyncTask(2:2)]: ASSERTION FAILED: !PtrTraits::is_null(bits)
[SyncTask(2:2)]: .././AK/RefPtr.h:457 in T* AK::RefPtr<T, PtrTraits>::as_nonnull_ptr(FlatPtr) const [with T = Kernel::Ext2FSInode; PtrTraits = AK::RefPtrTraits<Kernel::Ext2FSInode>; FlatPtr = unsigned int]

The 2 GiB mark is pretty suspicious, as the sign bit is set and we've had multiple issues with sign bits: #4584 #4585 #4615
