installing vanilla kernel in parallel with intel eci

[grandixximo]

Just wondering why this does not work well anymore, I like to have the venilla kernel there just in case, but seems like ethercat dkms does not work well with the latest linux-image-amd64 or linux-headers-amd-64 which will install  linux-image-5.10.0-29-amd64 and  linux-headers-5.10.0-29-amd64
Does anyone run ethercat with ECI kernel and vanilla kernel?
I didn't see any suggestions to remove the vanilla kernel.

Hi,

Generally, the latest officially validated Linux kernel/OS to be used with ECI is Canonical Ubuntu 20.04 (Focal Fossa) or Canonical Ubuntu 22.04 (Jammy Jellyfish).

You may refer here.

Other kernels might or might not properly work with ECI and issues are expected.

Cordially,

What about Debian bullseye is it not supported anymore?

We'll further clarify this and get back to you.

Thank you very much for the reply,

If you need any more clarification let me know, the issue is updating or isntalling kernels with ighethercat-dkms installed

[grandixximo]

I found that the problem is with the dkms.conf in the ighethercat-dkms package, on line 3 we see

BUILD_EXCLUSIVE_KERNEL="^((5\.(1[05])\.)|(6\.1\.))"

specifically with this line, this will try to install on any 5.10x 5.15x or 6.1x

I found that the ighethercat-dkms in the eci repos only play nice with intel-ese kernels

how about changing this line to 
BUILD_EXCLUSIVE_KERNEL="^((5\.(10|15)\.)|(6\.1\.)).*intel-ese"
So that the regex will allow only intel-ese kernels to automatically get the ighethercat-dkms installed.

Hi,

Glad to know that you've solved the issue.

You may refer to this ECI release note as it mentions which open-sourced components were updated in the respective ECI release

Intel will no longer monitor this thread since this issue has been resolved.  If you need any additional information from Intel, please submit a new question.

Cordially,
