Comment # 5 on bug 1207807 from Alexander Krupp

Thank you for pointing out the issue including the trace-cmd. 

I am running at present with linux memory compaction enabled, but with VMware
page trimming disabled as suggested in
https://bugzilla.redhat.com/show_bug.cgi?id=1694305#c12

The issue did occur less frequently over the past hours, but it still happens.
I can trigger it at will by issuing:

echo 1 >/proc/sys/vm/compact_memory

Result: the vmware guest freezes instantly for approx. 25s.

The trace I uploaded was started ~ 2s before memory compaction was requested
and it was stopped once the guest unfroze. 

I hope that helps somewhat. 

My kernel is 

Linux en-pc82 5.14.21-150400.24.41-default #1 SMP PREEMPT_DYNAMIC Fri Jan 13
08:55:22 UTC 2023 (1d4442d) x86_64 x86_64 x86_64 GNU/Linux

however the problem has haunted me for a couple of months, and across multiple
kernel versions already.
