 Turns out, that this card and main board (bios) have issues. The pci dump
 gives:
 
     Base address register at 0x14
       type: 64-bit nonprefetchable memory
       base: 0x40000000f7080000
       size: 0x0000000000080000
 
 the Bit 62 is set and exceeds the iomem range,
 
 On the previous board the value was:
 
     Base address register at 0x14
       type: 64-bit nonprefetchable memory
       base: 0x00000000fe180000
 
 which is much more sensible.
 
 Upgrading the BIOS made the BIOS start very slow and the card was not
 recognized any more
 
 except for delaying the startup from normally ~30 seconds to several minutes.
 
 Will close this bug.
 
 The Mainboard is an ASUS Prime X570-PRO with BIOS 1405
