NIC em problem on FreeBSD 10

K

Ken Chen

I have a very old server with two onboard Intel PRO/1000 NICs. On FreeBSD 8.4, they are recognized as em0 and em1. On FreeBSD 10, there are some problems with these NICs.

Any suggestions to this problem? Thanks.

I am not sure what your problems are, but Googling for "em0: Unable to allocate bus resource: ioport" yields results indicating you may want to try disable PnP aware OS in your BIOS or set hw.pci.realloc_bars=1 in the /boot/loader.conf file.

I have Googled this and tried this before, but it was not helpful. These NICs are fine on FreeBSD 8.4.

Using Intel 82573 nic built on my pdsbm-ln2 1U server and only one port will work. And my WIFI PCI card and dual legacy Intel NIC PCI will cause system to HALT on boot. If I pull those cards out the system will boot but only one port will work that is built on the motherboard. If I disable both with jumpers then I can use a PCI card in the system.

Refer to all the notes I did here

I have this in my loader.conf. I tried your hw.pci.realloc_bars=1 but it didn't seem to fix it.

Keep in mind Ubuntu and FreeBSD 8.1 and other distros do not seem to have any problem with this hardware. I've only found FreeBSD 10.1 to have this issue. What changed from 8.1 to 10.1 to kill my Intel built-in network ports?

Code: 
autoboot_delay="3"
vm.kmem_size="435544320"
vm.kmem_size_max="535544320"
hw.acpi.host_mem_start="0xf0000000"
boot_verbose="1"
comconsole_speed="115200"
hw.usb.no_pf="1"
hw.pci.realloc_bars=1
 
I too have the same problem, my older servers (six of them) not running with 10.1. It all started for me after the removal of legacy Xorg and it has been going all downhill since. I'm back to running 8.4 on all of them and they are all running fine. I lost usable support for Intel network cards and video cards plus two Nvidia video cards quit working. I hope you have more luck with your problem then I have.

Try setting 'hint.agp.0.disabled=1' in loader.conf. agp0 allocates a page of address space that causes a trickle down effect where em0 and em1 have to allocate different BARs.

That said, em0/1 should be able to cope with the alternate BARs, though it may be that em0 doesn't work because em1's bridge is still decoding those addresses when em0 tries to probe. I bet that if we forced em0 to reattach it would actually work ok (e.g using my devctl thing that isn't in the tree yet).

Ultimately this is a PCI bus bug, not an em(4) issue.

Is 'hint.agp.0.disabled=1' useful on your servers?
 
Thanks for posting this. This resolved my issue with pfSense after upgrading from 2.1.5 to 2.2 (FreeBSD 8.3 to 10.1) on a watchguard XCS570 with dual Intel Pro/1000 onboard ports. Both ports in dmesg appeared named em0 with the same log messages as posted by topper727. Thanks again!
 
Unfortunately, 'hint.agp.0.disabled=1' not helpful for my very old server. After much Google, to disable New PCI-PCI brige driver to solve my problem.

Code: 
nooptions  NEW_PCIB

If either 'hw.pci.realloc_bars=1' and 'hint.agp.0.disabled=1' are not helpful, I hope new kernel is helpful.

Should I report this issue on my so old server?
 
I guess you already have the newest BIOS installed etc. You should report it at least but given its very old hardware I don't think may be worth tracking it fully down.
For what its worth, my really old PCI-X dual NIC works fine (sits in a 32-bit PCI slot) out of the box so yours might be a rare fallout.

From what I can tell this is the successor of your controller, IPv6 offloading and some other minor differences.

Hello everyone,

I meet the same problem. I try to install pfsense 2.2.6 in NetAsq U70 Firewall Appliance. the chip is PC82573L Intel but... don't work :(

I changed a configuration file loader.conf with hw.pci.realloc_bars=1 and hint.agp.0.disabled=1 parameters.
but nothing.
Code: 
em0: <Intel(R) PRO/1000 Network Connection 7.4.2> port 0xbf00-0xbf1f mem 0xcfde0000-0xcfdfffff irq 16 at device 0.0 on pci130  
em0: attempting to allocate 1 MSI vectors (1 supported)  
em0: No MSI/MSIX using a Legacy IRQ  
ioapic0: routing intpin 16 (PCI IRQ 16) to lapic 0 vector 57  
em0: bpf attached  
em0: Ethernet address: 00:0d:b4:08:69:cb
