OK, can you post the blk-mq debugfs log after you trigger it on v5.17?
https://drive.google.com/file/d/1n8f66pVLCwQTJ0PMd71EiUZoeTWQk3dB/view?usp=sharing This time it happened pretty quickly. This log is soon after triple digit load and no IO, but not as fully developed as before. The system has become entirely unresponsive to new commands, so I have to issue sysrq+b - if I let it go too long even that won't work. -- Chris Murphy
