NI DAQmx on Ubuntu 22.04 with HWE?

[pieleric]

Hi,

I would like to use the NI-DAQmx on Ubuntu 22.04. It seems to work fine with the original kernel, v5.15 (to be precise, v5.15.0-91). However, if I use the newer kernel, from the "hardware enablement" stack, v6.5, the dkms modules fail to build. Essentially, when building nikal, it fails with:

  CC [M]  /var/lib/dkms/nikal/23.8.0f102/build/nikal.o
  MODPOST /var/lib/dkms/nikal/23.8.0f102/build/Module.symvers
ERROR: modpost: "__pte_offset_map" [/var/lib/dkms/nikal/23.8.0f102/build/nikal.ko] undefined!
make[2]: *** [scripts/Makefile.modpost:144: /var/lib/dkms/nikal/23.8.0f102/build/Module.symvers] Error 1
make[1]: *** [Makefile:1989: modpost] Error 2

This newer kernel does work better with my computer, so I'd rather use that one if possible. Is this error known? Is there already a plan to support this newer kernel soon?

Best,

Éric

This is a known issue.  I would expect this to be corrected in the coming quarterly driver stack release.  In the mean time, if you can somehow use the 6.2 HWE kernel, that may work.
