Just to be sure, is this with the 5.19 based kernel we used to use
(fe178cf0153d98b71cb01a46c8cc050826a17e77) or the "new" 6.1-rc3 based
one (ca67838d84af4c9f85d06311c9e98e1adf46308f)?

Sounds like access to an invalid address to me. When does this trigger?
Early doing Linux boot?

I see the mangopi mq-pro only has 512MB RAM. 0x5xxx.xxxx is at the very
end of that (memory starts at 0x4xxx.xxxx), did you update the memory
size in the device tree passed to OpenSBI?

I just did a clean rebuild of nezha_defconfig here, and it boots without
any issues:
