login to GUI desktop hangs when PCIe SSD is plugged in

[grimace]

I'm running Ubuntu 18.04  and have updated and upgraded everything.  If I plug in the PCIe card for my nvme SSD, boot up, everything works fine.  I can run mongo on the nvme drive no problem.  

As long as I don't log in ( to the desktop gui ), the system seems to work fine.  

Or, if I remove the PCIe card and reboot, I can log in to the GUI desktop.

The problem only happens when
   1.) PCIe nvme card is plugged in,  and
   2.) I log in to the GUI desktop.

Thoughts?

That's good to hear.  Is there an issue or bug that has been registered?

Yes, both on ayufan's git and in the thread on mrfixit2001 debian build

So it affects both builds/ kernels.

In short, for some (yet unknown) reason, the lockup only happens with pulseaudio is installed. If you would like to help then please connect UART and dump a couple lockups and provide them here.

Also, change extlinux to:

Code:

append console=ttyS2,1500000n8 rw root=/dev/mmcblk0p2 rootwait rootfstype=ext4 panic=10 init=/sbin/init coherent_pool=1M ethaddr=${ethaddr} eth1addr=${eth1addr} serial=${serial#} cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory swapaccount=1 video=HDMI-A-1:1920x1080@60 no_console_suspend initcall_debug
