Hello,
I have a Mellanox card, which is detected, however on one machine:
01:00.0 Network controller: Mellanox Technologies MT27500 Family [ConnectX-3]
Subsystem: Mellanox Technologies MT27500 Family [ConnectX-3]
Flags: fast devsel, IRQ 16
Memory at dfb00000 (64-bit, non-prefetchable) [size=1M]
Memory at <ignored> (64-bit, prefetchable)
and on another machine, it differs:
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at cf800000 (64-bit, prefetchable) [size=8M]
Obviously on the machine with <ignored>, I get a driver error, where
it works on the other.
[ 1.257148] mlx4_core: Mellanox ConnectX core driver v4.0-0
[ 1.257163] mlx4_core: Initializing 0000:01:00.0
[ 1.257196] mlx4_core 0000:01:00.0: enabling device (0000 -> 0002)
[ 1.257303] mlx4_core 0000:01:00.0: Missing UAR, aborting
I tried to use another 16x slot on the failing machine, and
even to update the BIOS: no change.
dmesg says:

I also tried to boot with an debian installer for testing and I had
similar PCI messages above.
What could I try to do?
Chipset on the failed machine is somewhat older than on the working
machine.
Thank you for any idea or pointer.
