I can reproduce this. Roll back to the 23.12.0.0013 firmware and all is ok. If I move to the 23.16.0-0018 firmware the corruption starts happening again.
If there is anything I can do to help your investigations let me know ASAP, I'd be glad to help.
I am sending this link to the LSI guys, did you show LSI your test results showing them this is issue? Seems our guys after testing believe they have reproduced the same issue.
My conversation with LSI ended when they told me I should replace my SSDs with ones on their approved hardware list. Frankly I've not found their first line support very helpful. If their first line support aren't listening to their customers problems but are trying to find excuses for not helping then it doesn't surprise me it takes them weeks for them to recongise a problem with their firmware. Hopefully you'll be able to escalate this to someone who will take notice.
Glad you guys have been able to reproduce the issue, I was starting to think I was alone in having this problem.
