I've run a few automated bisection on kernelci.org, it initially landed on this merge commit: ff719be3476a Merge remote-tracking branch 'scsi/for-next' The 2 parent commits boot fine, but not the resulting merge. So I did another bisection based on the first branch while merging the incoming one in each iteration, and that landed on this commit: commit d5038a13eca72fb216c07eb717169092e92284f1 Author: Johannes Thumshirn <jthumshirn@xxxxxxx> Date: Wed Jul 4 10:53:56 2018 +0200 scsi: core: switch to scsi-mq by default I then tried to revert it on top of next-20180731 and it did make it boot again. Now, I haven't looked much further in the code, it's entirely possible that the problem is on another incoming branch, in the code that this config enables. At least it seems to be narrowing down the scope for where to look for a problem. Hope this helps! Best wishes, Guillaume [...]
