Hi. We have:

proxmox shows this in dmesg:

pci 0000:04:06.0: address space collision: [mem 0xfe600000-0xfe63ffff pref] conflicts with PCI Bus 0000:04 [mem 0xfe600000-0xfe6fffff]

We are using 3 NICs in our server (snippet):

lspci:
00:04.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RD890 PCI to PCI bridge (PCI express gpp port D)
04:06.0 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) (rev 01)
(HP NIC with two ports!)

My first thought was: pci=nocrs in /etc/default/grub but it made no difference.
Besides the network in our VM is slow ... very slow! The VM-Server offers PXE-boot but not with high
performance
Any ideas what to do?
Thanks!
