Intel 10Gbit Card X540-T1 changes its Hardware ID?

Hi,

 

we have bought 3 of these expensive cards and for the second time now the following has happened:

 

these cards came as

 

PCI\VEN_8086\DEV_1528\&SUBSYS_00028086

 

and the installation of the the newest Win7 64bit drivers 20.3 went just fine and the network card worked

perfectly. The problem now is, once the PC shut down/cold booted the network disappeared and instead

an unknown ethernet controller is found by the device manager listed as follows:


PCI\VEN_8086\DEV_1512\&SUBSYS_00008086


It is then of course not possible anymore to install any driver for it, not even manually

inserting DEV_1512 into the .inf file works (device cannot be started code 10). Also

the Ctrl-S dialog to get into the card doesn't come up anymore after the Bios screen.

It looks as if the card is brain dead or several bits flipped or whatever.


This is now the second time under Win7 64bit with an HP 8100 Workstation. Under

Win81 64bit on a 2 Dell workstations the cards work very well even after several

complete shutdowns.


What can we do? Why and how does this happen? I have already RMA'd one card

and got a replacement but now the same is happening again and we can not believe

what we see. Hardware ID's are changing, how's that possible, what's going on??


What should we do with this, does anyone have any idea how this can be fixed???

Any help please? Thank you!
