Title:
Kernel 4.4.0-39 fails to detect NVMe SSD
Status in linux package in Ubuntu:
Confirmed
Bug description:
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. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait for the right device?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=a5ccaf22-ffde-44c2-8c59-84a851f9fd90 does not exist. Dropping to
shell!

Picking the -38 kernel in the grub menu allows the system to boot normally.
