Hi, what type of PCI error is it showing in the logs? Can you show the output from

cat /proc/cmdline

The dmesg output

@orange-businessperson-74585 Add the kernel boot option

pci=nommconf

this will revert that memory allocation back to traditional. I use it here on my HP Z440 (openSUSE Tumbleweed). So that entry is in /etc/default/grub then you can run

grub2-mkconfig -o /boot/grub2/grub.cfg

afterwards to update, then reboot. Or at boot you can edit grub and add the option for that boot to see how it goes first.

I have added the kernel parameter at boot time to try it out first. The cpu is an 11th Gen Intel(R) Core(TM) i9-11900 @ 2.50GHz

So should only need the intel_iommu then.

Might want to update firmware of that card too. And in driver notes it says Disable LRO when routing/bridging.

LRO and GRO are disabled but problem still exists

ethtool -K enp3s0 lro off
ethtool -K enp3s0 gro off

@orange-businessperson-74585 did you run the grub2-mkconfig command after changing the options?

I mounted the boot partition and changed the parameters in de grub config file manually. Now is the question what to do with the intel_iommu parameter. I removed it completely but network card still stop functioning after a while. Should the intel_iommu be set to "off"?

No, it was just the amd_iommu one... since you have an intel cpu.

with

intel_iommu=on

and

pci=nommconf

the network card stops functioning after a while. ANy other ideas or tips?

Did you try as @brainy-whale-97450 suggested a firmware upgrade on the card?

I tried but ended up with a windows installation were I ran a DELL firmware update but it did not flash the firmware in the nic. There is not much information for updating the firmware on this card available.

From my quick searching, it looks like this card is not very well supported by marvell anymore. Maybe it is a lot faster and easier to go with a card that is well supported? https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=pcie+dua[…]10g&_sacat=0&LH_TitleDesc=0&_odkw=pcie+dual+rj45+19g&_osacat=0

Had the same conclusion, is there a list of supported hardware in harvester?

@orange-businessperson-74585 what is the output from

cat/etc/os-release

?

@bored-farmer-36655 the output is
