em0 kernel panic ?

[vso1]

I have 2 intel nics

1 is sending intermittent "data" the other one just bought (intel CT, PCIe nic 1000)
installed the intel provided 8.x module/driver

whenever i do ifconfig em0 x.x.x.x netmask x.x.x.x freebsd panic's and
with RX ring hdr and it dies ..


ps the other network card was first in an other machine (esxi) and had the same issues
I see now ..

how do i change back to de freebsd provided driver ?

I'm assuming you're loading the if_em module per Intel's instructions, so:
When you boot next/escape to a loader prompt (option 6, I believe), and type [cmd=""]unload[/cmd]
[cmd=""]load kernel[/cmd]
When your system is up and running, edit the

if_em_load="YES"

line out of your /boot/loader.conf.

The em(4) driver should be in the GENERIC kernel, so you shouldn't have to do anything to use it besides configure the interface.

If you're not running GENERIC & you've removed "device em", remove the intel provided driver (it should be in /boot/modules/if_em.ko), and load the driver from /boot/kernel/if_em.ko.

If the intel provided driver overwrote your /boot/kernel/if_em.ko, then

• make sure you have the kernel sources in /usr/src/sys/
• # cd /usr/src/sys/modules/em/ && make obj depend all install
• put the

  if_em_load="YES"

  back into your /boot/loader.conf
• reboot

 

[vso1]

error still there
I did:
1) remove line from /boot/loader.conf
2) intel overwrites /boot/kernel/if_em.ko (checked install)
assuming the the following overwrites intell's driver install
3) # cd /usr/src/sys/modules/em/ && make obj depend all install

but unfortunally I still get the "RX ring initiliazation hdr" kernel panic
ps I build my kernel with em driver included

so if I did correct where is the error I got 2 EM nic's in the machine
the other (em1) doesn't error when I set an IP (it has an other issue)

Hmm, this does look like something you might want to try asking on freebsd-questions@, though they'll probably want the output of dmesg(8), & pciconf(8) ([cmd=""]pciconf -lv[/cmd]), which you should probably post here as well.

pciconf -lv

gives:

ps I was running 8.1-rc2 now upgraded to 8.1-release (gone try that)

how do I add things from HEAD ?

 

[DutchDaemon]

You don't. You either run HEAD (now 9-CURRENT), or you wait for stuff to be backported to 8-STABLE. Library differences and other incompatibilities between these major versions precludes lifting code from the one and running it in the other without porting.
