Created attachment 1458908 [details] dracut log Description of problem: Ever since Fedora released 4.17.x kernels, my MacBook Air (7,1) hangs during boot when attempting to use the nvme disk controller, with messages such as: [ 32.742056] llamamac kernel: nvme nvme0: controller is down; will reset: CSTS=0x3, PCI_STATUS=0x810 [ 32.767211] llamamac kernel: nvme nvme0: detected Apple NVMe controller, set queue depth=2 to work around controller resets [ 48.368123] llamamac kernel: nvme nvme0: Device not ready; aborting reset [ 48.368181] llamamac kernel: nvme nvme0: Removing after probe failure status: -19 [ 132.401562] llamamac dracut-initqueue[330]: Warning: dracut-initqueue timeout - starting timeout script Version-Release number of selected component (if applicable): 4.17.5-100 How reproducible: Attempt to boot from any 4.17.x kernel. Actual results: [ 195.331272] llamamac dracut-initqueue[330]: Warning: dracut-initqueue timeout - starting timeout scripts [ 195.331902] llamamac dracut-initqueue[330]: Warning: Could not boot. Expected results: OS fully boots without hanging. Additional info: Does not reproduce at all when booting with 4.16.14-200.fc27.x86_64. I've attached the dracut generated rdsosreport from a hang.
I thought this might be the same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1599042 , so I tried booting the 4.17.x kernel with: nvme_core.default_ps_max_latency_us=0 but that had no impact.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 27 kernel bugs. Fedora 27 has now been rebased to 4.17.7-100.fc27. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 28, and are still experiencing this issue, please change the version to Fedora 28. If you experience different issues, please open a new bug report for those.
Not fixed with 4.17.7-100.fc27

Not resolved. Still fails to boot.
Same failure with Fedora28. The original 4.16.3-301.fc28.x86_64 kernel boots fine. Anything & everything starting with 4.17.x fails.
The Vanilla-Kernel from kernel.org have the same problem. 4.16 is the last usable kernel for my small Macbook Air 2015 (7.1)
Thanks Robert. I've opened up a kernel.org bug now as well, in the hopes that maybe this will get more attention upstream.

This is *NOT* fixed with the latest Fedora 28 kernel (4.20.5-100.fc28). Fedora29 won't even install, due to this bug. This bug is a complete blocker on using Fedora.
This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '28'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Its impossible to even install Fedora29 due to this bug.

Its impossible to even install Fedora31 due to this bug. I have little doubt I'll be back here in another 6 months to report the same is true for Fedora32.
I am experiencing the same thing on certain kernel versions on Fedora 32. My bug is filed here: https://bugzilla.redhat.com/show_bug.cgi?id=1878596
