|
|
Built a new system yesterday, installed Gentoo. Went fine. Spent this afternoon setting up X and my desktop. At some point I realized my network was no longer working.
Repeated attempts to restart the interface only resulted in being assigned a "link local" address 169.254.8.87. The system uses dhcp and typically gets assigned an IP something like 192.168.2.10. Also started getting this in dmesg:
Code: |
r8169 000:02:00.0: Direct firmware load failed with error -2
r8169 000:02:00.0: Falling back to user helper
r8169 000:02:00.0 enp2s0: unable to load firmware patch rtl_nic/rtl8168d-1.fw (-2)
|
Did some searching, seems you have to load firmware for this driver? emerge linux-firmware? I never did that. '/lib/firmware' doesn't exist.
How does a nic that worked fine for the installation, and a day and half after suddenly decide it needs firmware?
Can't ping my gateway, can't ping anything. Decided to fire up the install CD again to see about downloading the firmware. The exact same CD that auto-detected and configured the interface yesterday is now giving me the same link local IP address. What?!?!?! The install CD is NOT giving me the dmesg errors however. So I even reset my BIOS to defaults, even though the only thing I changed was adding the IOMMU device.

NIC is an onboard, using driver r8169 built in to the kernel.
I have no idea what even to look for here...just baffled and confused. _________________ "...the number of UNIX installations has grown to 10, with more expected..."

Well, I dunno.
After trying 10-15 or so permutations of various kernel configurations the box is back online. I'm hesitant to mark my problem as 'solved' however, as certain things still seem to be flaky. For instance...from the console I attempted to ping google, but it just hung and did nothing until I ctrl-c'ed it. Did that several times, but after firing up KDE ping works just fine from an eterm. Not sure if that is related in any way.
I took the opportunity to emerge linux-firmware, so now the firmware that the kernel was complaining about is on disk. I gather this is relevant to the kernel config CONFIG_FIRMWARE_IN_KERNEL. Set to yes it builds the blob into the kernel, and if no it looks in /lib/firmware and loads from userspace. Is that right?
I also noticed there is a r8168 driver in net-misc. I tried to emerge it but it failed because I have r8169 built in to the kernel. So I guess my next step will be to build a kernel without r8169 and try the r8168 driver.... _________________ "...the number of UNIX installations has grown to 10, with more expected..."

This post is super old an old, but run "ethtool -i eth0". This will show you, if the firmware has been loaded. _________________ cya |

Because the r8169 support is compile in the kernel image, the firmware files that r8169 need should be compile in the kernel image too. If not, when the NIC is probe and detected by the Linux image, the r8169 support will not have access to the firmware files it need until the real root partition will be mount. This can be the problem.
That's why I always compile the NIC support in module. Than when the module is load, the real root partition is mounted and the module have access to the firmware files too. _________________ Paul |

Does the card work at first and after some time suddenly stop working? This could be an IOMMU issue (especially on AMD systems) and worked around by iommu=pt kernel parameter.
If the card never works, the missing firmware could be at fault. If the driver is compiled into your kernel, then also the firmware file needs to be built-in (through CONFIG_EXTRA_FIRMWARE). If r8169 is a module, then installing the linux-firmware package should be enough. |
