Created attachment 301393 [details] kernel dmesg (kernel 5.10.129, without PAGE_POISONING, Talos II) Found that out during investigating bug #216183 closer. On kernel 5.10.x LTS the Talos 2 boots fine with HASH MMU used. But the same kernel .config fails to boot when CONFIG_PAGE_POISONING=y is set and used. I get no netconsole output then, only a reboot after a while.
