Hello.
Changing settings mean speed/duplex, NIC hangs even if no cable inserted. All setting don't use KVM, only RDP to server using other NIC or direct control.
I tried to use Diagnostics from PROSet, it success all tests except last, on last test it hangs also and test didn't finish.
I'm from Russia, shipping to other country using RMA is long time, but if no chances to alive this card, I'll try.
Regards,
Kirill
