From the debugfs log, hctx0 is mapped to lots of CPU, so it shouldn't be
unmapped, could you check if it is hctx0 which is unmapped when the
warning is triggered? If not, what is the unmapped hctx? And you can do
that by adding one extra line:
printk("unmapped hctx %d", hctx->queue_num);Where do you want that printk?
Thanks, Ming
