Hi Michal,
When I bind my interfaces to igb_uio, I maintain the bus master
flag. Can you describe the hardware layout? Are you using any kind of
PCI multiplexer/riser?
Also, what is the output to 'lcpci -t'? That might give us some
additional interesting information.
Regards,
Dave
Michal,
I looked a bit deeper into the specs of the HP-Z200 workstation. It
has only 1 PCI gen2, and the rest are PCI gen1. Only one of the 16x
slots is gen2.
Could you confirm in which slots a single NIC will work? You can use
"lspci -vvv -s 18:00 | grep LinkSta" to see the speeds when its installed.
Does a single NIC work in all slots?
Does it only work on the Gen2 16x slot?
If you put 2 NICS in 2 gen1 slots, do any of them work?
Regards,
Dave.
