            Bug ID: 216238
           Summary: Kernel 5.10.129 fails to boot on a Talos 2 with HASH
                    MMU (PPC_RADIX_MMU not set) with
                    CONFIG_PAGE_POISONING=y
           Product: Platform Specific/Hardware
           Version: 2.5
    Kernel Version: 5.10.129
          Hardware: PPC-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: PPC-64
          Assignee: platform_ppc-64 at kernel-bugs.osdl.org

Created attachment 301393
  --> https://bugzilla.kernel.org/attachment.cgi?id=301393&action=edit
kernel dmesg (kernel 5.19-rc4, 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.
