Brad, Sujith is on vacation until 1/22/2019. We will try to find someone to verify. But if we are not able to locate, What is the plan to mitigate waiting for Sujith to return? --jerry

The drive's admin queue (queue 0) times out, making the nvme device driver flag an error and reset the controller. This bug is fixed by commit 62843c2e4226, which is in mainline as of v4.17-rc1. == Fix == 62843c2e4226 ("nvme: Use admin command effects for admin commands") == Regression Potential == Low. Limited to nvme driver. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug. Every time you run an nvme format on a Intel NVMe drive (whether specifying the secure/crypto erase options or not), the format apparently works (drive is wiped clean) but the drive's admin queue (queue 0) times out, making the nvme device driver flag an error and reset the controller. Here's an example: nvme-cli-1.5 # ./nvme format -l 0 /dev/nvme1 NVME Admin command error:ABORT_REQ(7) nvme-cli-1.5 # dmesg|tail -1 [79725.404910] nvme nvme1: I/O 151 QID 0 timeout, reset controller Patch required: https://github.com/torvalds/linux/commit/62843c2e4226057c83f520c74fe9c81a1891c331 Request you to include the patch for LTS kernel 4.15 of Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-poweredge/+bug/1797587/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
