I rented a Linode and have been trying to load it down with sysbench
activity while doing a mariabackup and a mysqldump, also while spinning
up the CPU with zstd benchmarks. So far I've had no luck triggering the
fault.
I've also been doing some kernel compilation. I followed this guide:
https://www.dwarmstrong.org/kernel/
(except that I used make -j24 to build in parallel and used make
localmodconfig to compile only the modules I need)
I've built the following kernels:
6.1.123 (equivalent to linux-image-6.1.0-29-amd64)
6.1.122
6.1.121
6.1.120
So far they have all exhibited the behavior. Next up is 6.1.119 which
is equivalent to linux-image-6.1.0-28-amd64. My expectation is that the
fault will not appear for this kernel.
It looks like the issue is here somewhere:
https://www.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.120
I have to work on some other things, and it'll take a while to prove the
negative (that is, to know that the failure isn't happening). I'll post
back with the 6.1.119 results when I have them.
