Pre-boot DMA Protection issue with Intel X610-XT2 NIC

noarch — Wed, 22 Apr 2026 07:15:51 GMT

I'm using drivers 1.7.44.0 from 2026-02-18 on a Dell Optiplex 7020 and it seems the X610 NIC has issues with Pre-Boot-DMA Protection, as it looses connectivity during boot time.

Disabling said DMA Protection resolves the issue, but I'd like to keep this option on.

Is this the expected behavior?

Hi Dineshbabu,

this is a PCIe networking card "Intel® Ethernet Network Adapter E610-XT2"[1] which I added to my Dell Optiplex by myself.

The driver in use is Intel(R) Network Connections Software, Release 31.1 for Windows 11 from 2026-03-01, the driver version and date given above was displayed in my computer management.

Since 31.1 is the latest Intel driver I tried downgrading, but that didn't seem to have any effect.

Nothing noteworthy, ixw logs with error 27:

The network connection has been lost.

Multiple GPOs throw errors for not beeing able to be applied.

And broken network shares, but this is all expected, if the NIC loses connection during boot-up as initially stated.

So is this expected behavior of this hardware? Is Pre-Boot DMA protection not supported by the
