Status: NEW
Severity: normal
Priority: P1
Component: PPC-64

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.
