VTY shell freezes after a few seconds?

Hi,

I'm experiencing an odd issue; I don't start the X server at boot however, after a few seconds the VTY will just freeze totally?

The system hasn't hung as I can still access over the network via SSH, and the X server when started (via SSH) works fine.

Basically after a few seconds there is no keyboard input, though at first it does work. So after logging into user account I can use it properly before it will just freeze and I will forced to login through the network using SSH.

Last night after a kernel update it seems the issue got remedied but after a reboot seems to have come back.

Kernel version is: 3.17.3-1 64 bit

The actual system is a Zotac D2550 ATOM mini-itx board

keyboard is standard USB PC keyboard

On boot there was a kernel message about something needing to be run with update, but it went too fast for me to catch and couldn't find it in my logs again. I wonder if that's the issue?

Could anyone suggest something I could try in order to be able to debug this? I can provide more information if needed, though at present I'm not sure what. I also attempted to search for the issue but most results came back with kernel freeze which isn't what I'm experiencing as it seems to be either related to usb devices or the VTY shell specifically.

Thanks.

[EDIT]

Actually I have just tested and keyboard is not functioning even when running the X server - though it does function at first like stated above.

Quick extra edit, did some more digging:

https://bbs.archlinux.org/viewtopic.php?id=185273

seems related.

GPU is Nvidia! forgot to mention that; lspci mentions it as GT610 - currently using "nvidia" package perhaps I should be using one of the other ones?

Re: VTY shell freezes after a few seconds?

Which shell are you using?
Does it happen with a new user using bash?
Is there anything interesting on the logs or journal?

Re: VTY shell freezes after a few seconds?

The shell is Bash, however I am not sure if it's the shell or VTY directly?? Basically it seems that the input doesn't work any more after a few seconds.... perhaps something to do with USB layer in kernel?

Shell otherwise from SSH is fine (Bash again). Also cursor is flashing but just no input after a while.

Unfortunately I don't see anything

Output of dmesg just shows:

Nothing related in journalctl.
