Black screen and blinking cursor after selecting anything from FOG menu

jam1987 · Jul 23, 2019, 8:06 PM

Hello!

I recently updated FOG to 1.5.7 and seem to have hit a snag.

FOG: 1.5.7
OS: Centos 7

When trying to do anything from the FOG menu after PXE booting I get a black screen with blinking cursor.

The PC’s are a mixture of Desktop and Laptop machines, all with Safe Mode turned off and UEFI/Legacy mode turned on with trying legacy first on boot.

Any help would be great.

Thanks.

@jam1987 Please open the following URL in your browser and post the text output you get here: http://x.x.x.x/fog/service/ipxe/boot.php?mac=aa:bb:cc:dd:ee:ff (put in the FOG server IP instead of x.x.x.x and a host’s MAC address as parameter)

Which exit type do you use? Has this ever worked before?

From which version did you upgrade to 1.5.7? I am not aware of any change between 1.5.6 and 1.5.7 that would cause this.

You helped me the other week getting FOG upgraded to 1.5.6 from 1.5.4 I had to change some settings in relation to MariaDB-client and server for the upgrade to progress.

Since then I haven’t needed to use FOG until today where I noticed the 1.5.7 update so I ran it and now seeing the issue…

Exit type is:

In the past it has always worked fine for me. I would either add the client to FOG via the web interface or the FOG PXE menu.

Capture image, check compatibility etc all worked. Instead now I get a black screen with a blinking cursor.

I just tried adding a blank laptop to FOG, added it as a host and gave it a blank image and ran a capture.

Rebooted and it is now sitting here:

@jam1987 Did it all work perfectly fine before you updated? Which version did you update from?

Have you tried booting a couple different hardware models? Do they all sit with the same blinking cursor when they should be booting from the hard drive after the FOG menu?

The menu code you posted looks ok in first sight.

In the picture I notice it’s loading bzImage4.19 which is not the default kernel. What kind of modification is this? I am not saying this is wrong or causing the issue but it’s something I notice and I try to get the whole picture.

jam1987 · Jul 24, 2019, 12:10 PM

@Sebastian-Roth , while using 1.5.4 all worked perfectly fine. I updated to 1.5.6 recently but did not need to use it. Logged into to use it yesterday and 1.5.7 popped up so I updated and now it’s not working.

I’m using this kernel currently, which was auto enabled during the install:

I’ll try it on another piece of hardware.

Sebastian Roth · Jul 30, 2019, 9:24 PM

@jam1987 Again I am wondering why we see bzImage4.19 in the picture. This is not booting the currently 4.19.48 kernel I suppose.

I am having the same issue, with the black screen and blinking cursor in the upper left corner after the Fog splash screen to boot to Hard Drive. So far it is isolated to Dell Latitude 5570’s that I have found was there a fix?

Fog version: 1.5.5
bzImage Version: 4.19.6
bzImage32 Version: 4.19.1

Sebastian Roth · Oct 11, 2019, 9:45 PM

@Brad-Schumann From what you wrote so far I am fairly sure this is a different issue than we had before. Please open a new topic and post more details on when this is exactly happening. When there is a task scheduled or if you try to register the host or what?
