system stuck at "started dynamic system tuning daemon"
On of my systems is stuck at "[ OK ] started dynamic system tuning daemon .mon....t certificates......ger...." and does not login in graphical UI. I can spawn another shell and login normally but I am unsure what to do to fix this.
Using RHEL 7.5 with kernel 3.10.0-862.9.1.el7.x86_64

Hi Paolo,
You need to provide some more comprehensive information about what you've done, otherwise we won't be able to help you.
Did you apply new updates ? Did it work properly before ? Which graphics card is in use ? Which graphics drivers are in use ?
Regards,
Christian
I have the same issue on Redhat 7 with Nvida Geforce gtx 1080. It worked fine before I update the red hat. Afyter YUM update finished and rebooted, the system is stuck at this stage.

Hi Farshid,
We've got a new kernel yesterday - it fixed the L1TF issue ... do you by chance have the proprietary NVIDIA drivers installed ? If you didn't install the dkms version (dkms is available from the EPEL repos), you need to reinstall the drivers. But that's just some kinda guessing, please read RJ's post, he's definitely right, with nearly no information provided, we're not able to help solving things like your problem professionally. :)

Paolo Berto, Rarshid Miri, and anyone experiencing this issue...
If possible, please provide more details...
Here's some initial thoughts - Did you (or did you not) recently perform an update against this system? I assume you're using a graphical environment such as (perhaps) GNOME and the system will not reach graphical login.
Try the previous kernel. At the GRUB splash screen at boot time, press any key to enter the GRUB interactive menu. Select Red Hat Enterprise Linux with the previous version of the kernel (probably the second choice from the top)
One other possibility that we are not sure if it applies from the limited information you provided, maybe there is a chance an important file's SELinux context has changed and the system will not boot properly as a result. Now I found this possibility when I googled the subject line of this original post as one of the many possibilities with the limited information we have.
See if booting into the previous kernel works. If it does, then a recent update may have caused issues for your system.
One possibility from the limited information in your original post (see Christian's point above), is that you might need to reload a graphics driver, and we don't know if you might possibly be using AMD or NVIDIA or... not.
You can boot into the rescue kernel or manually enter the grub line and boot to a different run level (perhaps multi-user.target) and that is where (if this is the case, we do not know) reinstall the graphics driver, again, if this is the case because we don't have details and we're just taking a wild stab here.
Please come back with more relevant details.
Regards,
RJ
