Hello Andrew, Alexis Huxley reported a bug against the Debian kernel where his x86_64 system died on a list corruption in rmqueue_bulk running a 6.1.129 kernel. Find below the output of the first BUG. Further details and logs are available at https://bugs.debian.org/1101944.
The problem isn't reproducible, so Alexis cannot reliably confirm if newer kernels are fixed. Alexis ran a memtest on that machine over-night without any reported problems. Does this ring a bell for you?
