In light of the last few comments here I can say that I may have been confusing 2 separate issues: The random segfaults and the lockups.
I tested idle=halt a while back and I may have inadvertently concluded that it didn't work due to my machine still receiving segfaults, which I was assuming would eventually lead to a lockup.

Likewise, the solution I mentioned earlier (disabling PAGE_TABLE_ISOLATION) seems to have fixed my crashes, but my machine just locked up.

I've set idle=halt again and this time I'll try to keep the two issues separate and only post back here if I still receive lockups.
Thanks for clarifying the issue.
