nvme device timeout

[Tim Mohlmann]

Hi,

During boot my nvme device is not showing up. I've found the following
dmesg output from nvme:
[    0.634251] nvme 0000:04:00.0: PCI INT A: no GSI
[   61.703015] nvme 0000:04:00.0: I/O 0 QID 0 timeout, disable controller
[   61.704028] nvme 0000:04:00.0: Identify Controller failed (-4)
[   61.705016] nvme 0000:04:00.0: Removing after probe failure status: -5

lspci does not list device anymore.

This problem occured after upgrading my kernel from 4.4.5 to 4.5-rc7.

I'm new to posting about bugs in the kernel, so please advise how I
can provide you with more meaningful info.

Regards,

Tim
