OK, this really is not the first time we're seeing the issue, but it was harder to correlate after a myriad of config changes, like turning off selinux in the kernel config. This was with OpenZFS @ 8f2f6cd: step_into ends a bit earlier b/c there's selinux in the mix

Interestingly, while this happens, arc_evict and arc_prune are both active at 70-100% cpu each. This is a list of processes in D state with their stacks after a few processes died with ^ similar oopses: |
System information
Describe the problem you're observing
Turns out the problems logged in #16594 were always early after the machine has booted, but that wasn't the problem causing the crashes, this seems to be it. After we applied fix for the Bad Page State bug (b052035), this is what we're left with, at least it's without noise now :D
