Hi all,
hopefully it's ok to reply-all at this point

I have a few quick additional questions already:
1. For clarification.. From your text, I understand that only this one
single server is showing the problem after the Debian version upgrade.
Does this mean that this is the only server you have running with
exactly this combination of hardware (and BIOS version, CPU microcode
etc etc)? Or, is there another one with same hardware which does not
show the problem?
This is the unique HW combination in terms of server type Dell R750xs
and CPU type 'Intel Xeon Silver 4310'
2. Can you reply with the output of 'xl dmesg' when the problem happens?
Or, if the system gets unusable too quick, do you have a serial console
connection to capture the output?
in attachment
3. To confirm... I understand that there are many of these messages.
Since you pasted only one, does that mean that all of them look exactly
the same, with "1 of 1 multicall(s) failed: cpu 10" "call 1: op=1
arg=[ffff8888a1a9eb10] result=-22"? Or are there variations? If so, can
you reply with a few different ones?
all looks exacly same, only 1 of 1 multicalls failed with same result

in faulty state (linux 6.1) and also in good state (linux 5.10), the
directory /sys/kernel/mm/transparent_hugepage is not present
we have also tried to boot with 'transparent_hugepage=never', but it
make no difference
