Hi all,
I have 2 bare metal Debian 12.4 servers with fairly new Intel CPUs and
plenty of memory.
On both, dmesg continuously reports:

$ sudo dmesg -T | grep cli64 | wc -l
1349
Other than that, they seem to be running ok.
I don't see it on similar, AMD powered kits.
Somebody suggested a faulty memory module. Or software trying to access
a restricted part of the memory. I'm not convinced.
Any ideas or hints?
Cheers,
Adam
