Public bug reported: After updating to linux-image-4.4.0-39 the system fails to boot because it is unable to find any boot device [1].
The output looks like this: (this is not my exact output but it is very similar) ----------------------------------------------------------------------------------- [ 1.452270] genirq: Flags mismatch irq 0. 00000080 (nvme0q0) vs. 00015a00 (timer) [ 1.452551] iounmap: bad address ffffc90001b88000 Scanning for Btrfs filesystems Gave up waiting for root device.
