Transition between ELILO and actual booting slow on Slackware64 -current

The_Dark_Passenger · 02-18-2021, 02:06 AM

Hello,

I have a Dell Precision 7920 tower running Slackware64 -current with the latest updates. I have configured the system to use the generic kernel. I've noticed however that the transition between ELILO and when the system actually begins booting is quite slow. ELILO loads the initrd and kernel without error and it displays that is done quickly. However, it will then sit there for about 20 or so seconds displaying this message before transitioning to where the system is booting. I was wondering is there any setting I may have missed to configure in ELILO similar to the "compact" setting in LILO?

I don't see anything odd in /var/log/messages or dmesg about why it takes this long between ELILO and the transition to booting.

System specs are below:

CPU: 2x Intel Xeon Silver 4116
GPU: NVIDIA Quadro P2000 (Running NVIDIA driver 460.39)
RAM: 64GB ECC DDR4-2400

Any ideas on what might be causing this is appreciated!

What is in dmesg the line it's hanging at (before the time gap) ?

Thanks for replying! Below is the very first things occurring per the dmesg output:

I'm just not really seeing any specific error occurring that would cause this. The hangup occurs before the boot process seems to really begin, it occurs before the output of the initrd modules being loaded, etc.

Since it is mentioned that "Secure Boot cannot be determined" is it possible you also run Windows or by any other means have Secure Boot enabled in BIOS/UEFI? Fast Boot is sometimes a problem in some systems so it might do well to try toggling that setting as well as be sure you have the latest available BIOS/UEFI firmware flashed. It would also be of some help to see your eliloconfig entries or you could try employing rEFInd and following the refind.conf notes for specifying conditions and options.

Also the lines with a timer gap seems to involve ACPI.
Maybe BIOS related as said above ?
