Kernel 4.1.6 causing "ata_id[] node not specified" from udev.

GazL · 08-23-2015, 06:32 PM

Since the bump to 4.1.6 I'm seeing the following message when udev is triggered during boot:

Code:

ata_id [288] node not specified

As far as I can tell it's being caused by the following rule in
59-non-libata-devices.rules:

Code:

# by-id (hardware serial number)
KERNEL=="hd*[!0-9]", IMPORT{program}="ata_id --export $tempnode"

My guess is that its a false match against the 'hdaudio' device(s), which appears to have had a name change compared with older kernels (3.14).

Adding SUBSYSTEM=="block" or something similar to tighten up the match is one possible approach to fixing this, but given that the old ide stuff is obsolete now and has been removed from upstream udev it might be better to just remove this rules file completely. Does udev even have a '$tempnode' now? The udev man page doesn't mention it.

I haven't seen these messages in eudev myself, yet, but I know since Slackware's udev-182 has been out, a lot of changes were made to the kernel and udev both, so some legacy stuff might be getting phased out.

By the looks of it, the file is a concatenation of a number of old rules files that Pat has carried forward from previous versions of udev. I doubt you'd encounter the issue outside of the slackware implementation, so I'm not surprised you're not seeing it with eudev.

I have the original rules, and they are installed, but I don't think eudev is using them for some reason. 3.1.2 from what I can detect, has been using its own self generated rules and automatic detections for some devices. I was thinking of trying to grab a few extra rules from LFS, for example, as well as their rule generator scripts to see if I'm missing anything.

That was one of the reasons I had to import 70-persistent-net.rules to get control of eth0 as a device node.

I did some reading and it seems some syntax was changed after udev-197, but to what degree I have no idea, yet.

Hi,

I'm running Slackware 14.1 with kernel 4.1.x (now 4.1.6) for quite some time and have also observed this message.

If you don't want to wait for a fix, then just run the following as root:

Code:

echo '# No-op: 59-non-libata-devices.rules' > /etc/udev/rules.d/59-non-libata-devices.rules

Worked for me (Slackware 14.1, kernel 4.1.6).
