Bios error during lcnc start

He.

I have a 5i25 in a HP workstation.
The computer works fine until I want start lcnc. It reboots and gives this error tlp poisend on pci slot.

Does anyone have any idea what is going on?
I did have some difficulty getting the card in.

Hard to tell, it might be a connection issue causing a parity error
in that slot or some unknown incompatibility.

Does lspci show the card?

lspci | grep 2718


 

Try disabling secure boot and TPM in BIOS.

Tpm is disabled
Also the device is visible in:
lspci | grep 2718

Seems to be a commonly found issue, HP support forums discuss this quite a bit with various cards.
Might be an idea to google your issue, TLP poisoned, and see if there are any solutions. I wouldn't mention a specific card in your searches to begin with.
My first thought was if the card wasn't on a "whitelist" the PC may refuse to play ball .

Thank you for the help. After looking into some more i just grapped a different pc.

I think the card needs to be installed during the installation.

That way, its kernel module will be loaded during boot-up.
 

You're wrong, so very very wrong.
 

Linux loads hardware modules at boot time, no matter if it was plugged in during install or not.
Proprietary modules/drives will nor be loaded during install nor after, they will have to be installed separately, like NVIDIA or AMD ROCM drivers.
Linux is extremely good with this as you can even add hardware while the PC is running, granted that hardware does not require BIOS initialization, and it will happily load required modules, like USB video grabbers, and in some cases SATA and PCI-E stuff like hard drives and NVME if set to "hot plug" in BIOS.
I recall having to reboot the windows PC to be able to use the USB stick you just inserted...ah the trauma!!!

The driver for the Mesa PCI\PCIe cards are loaded during the startup of Linuxcnc.

Linux has no issues loading kernel modules for supported hardware that are added after installation, if this was not the case live versions of Linux wouldn't work, installers for Linux would fall over.

If you have ever read the output of dmesg you would see very clearly that the kernel detects the installed hardware and loads the kernel modules as required, or the hardware may have support compiled into the kernel. With the caveat that the kernel "knows about the hardware". There is absolutely no need for the hardware to be present during installation. For hardware that is "hot swappable" the hardware is not required to be attached/inserted/present during boot, it is detected when inserted, and no this is not limited to just USB devices.
I'm quite astonished at the amount of information you post that is wrong. This is quite a distressing matter as one day someone will take your advice as true and have a very bad experience. You really need to reassess your level of knowledge and take some time out and sit back and learn.
When you are not being wrong you are not addressing the subject matter and being unhelpful.
As I've suggested before read a book and learn.

That means if a PC running Linux happens to break, you can just take out the HDD and plug it into another PC and it will work no fuss, no muss.

Yes, for the last 20 odd years Linux could do that, even through external USB cases and/or CD/DVD rom's.
That is very hard to explain to "PC experts" who used windows only as that never worked, till win10 had that haphazardly implemented and intermittently working about 5% of the time.
