`ioctl` errors on latest kernel #8

Closed PeterBowman closed 2 years ago

PeterBowman commented 2 years ago

The kernel module is unable to communicate with the acquisition board on latest Linux 5.4.0-122-generic kernel (tested on pc3, which is currently running an Ubuntu 18.04 installation). I did manage to load it successfully at 5.4.0-121 and also at a still available 5.3.x kernel; use grub load screen to log into them.

Perhaps it's time to install a newer Ubuntu, which might automagically solve this issue.

So apparently it works on the latest 5.4.0-128-generic kernel upgraded today. See https://github.com/roboticslab-uc3m/jr3pci-linux/issues/7 and https://github.com/roboticslab-uc3m/jr3pci-linux/issues/6 regarding a countermeasure to avoid such errors in the future.
