Right, I'm aware. I staged the tree that made some HP servers finally work with the latest linux-block 4.16 changes. Without thinking about the broader implications. Anyway, I'll drop the revert from linux-dm.git's 'for-next'. Because I'm confident others will hunt down the irq issues. I think Ming was looking to grab the queue mapping info and CPU related info from the affected server. > Though I do note it actually has a reasonable commit message, thanks. Semi-reasonable. Lacks detail. The issue is that over the weekend Laurence found linux-block.git commit 84676c1f21e8ff54befe98 prevents some HP servers from booting. They'd hang when trying to initialize their HPSA controller's devices, e.g.: [ 246.751050] INFO: task systemd-udevd:411 blocked for more than 120 seconds.

Hi Mike, I have cooked a fix today, please see the following link: https://marc.info/?l=linux-kernel&m=151601867018444&w=2 This issue is clear, and has been described in above link and the patch. If no objection, I will prepare a formal version. -- Ming ^ permalink raw reply [flat|nested] 2+ messages in thread
