Touchpad works well either 5.14.0-427.33.1.el9_4.x86_64 and 5.15.0-209.161.7.2.el9uek.x86_64
But it doesn't work if I boot with 6.9.0-2.el9ueknext.x86_64

System settings in KDE shows "Touchpad not found" message

I can provide any additional information if you tell me the command I should run.

Hi @natomist

Could you please share these details, which might help us understanding the issue more.

  1. What rpms of UEK-next were installed ?
  2. What is the type of machine you are using ?
  3. Do you see a difference in modules related to touchpad from UEK7 vs 6.9.0-UEK-next ?
    a. difference between dmesg of both UEK7 and UEK-next kernels
    b. difference between $ lsmod , $ lsusb , $lspci outputs

Thanks,
Harshit

@natomist what type of touchpad is this? Builtin / USB / Bluetooth?

On a working system, can you provide the output of the commands lsmod, and depending on if it is builtin or not, lsusb -v and lspci -v

net/mlx5e: drop shorter ethernet frames
6e2e869 
Add a check to mlx5e_xmit() for shorter frames. A corrupted/malformed
packet, with shorter length can eventually cause system panic further
down in the code path. Avoid it by validating the length and dropping it
at the earliest.

Following is seen in our env with shorter skb->len
