T5500 turn off-on in cycle with a new PCIe Wi-Fi card

Hello. I recently got a wifi pcie card to spice up my old but powerful T5500 (dual Xeon X5660 with 48GB DDR3 ECC). The wifi card works fine but when I try to turn off the PC, it turns on by itself and turns off again after a few seconds, in an endless cycle. It only stops when I unplug the power cord, and happens again on the next power off. No BIOS events reported.
I have the latest BIOS version available (A16) but I can't find many options that may be related. I disabled WoL, internal NIC and C states, but no change.
Changing pcie slots makes no difference. The problem is solved when I remove the card.
There are no other problems with my T5500 except for this.
The wifi card is based on the Intel AX210 controller and I have all the latest drivers (Windows 10 x64).
Will there be any incompatibility or maybe some interference problem?
Do you know any workaround?

In the bios there should be an option to restart from the previous state in case of a power loss. Try to turn it off and see if it changes something

There are no changes. The on/off cycle persists.
