The imx6 vs. rk3288 > are pretty different platforms; Based on what you wrote, it sounds like it could either be a hardware-specific problem, or else a kernel-configuration-specific problem, since you used radically different kernel configurations in these two cases. If I understand correctly, 'linux-libre-arm-generic@5.4' is the variant that panicked on an rk3288, whereas the 'linux-libre@5.4' variant with our hand-crafted default configuration worked on an imx6. I don't know whether it's possible to use precisely the same kernel configuration on these two systems. Anyway, it would be helpful to retry the 'iwd' build on these two devices with kernel versions and configurations that are identical except for a minimal set of required differences. That would help us narrow down the set of possible causes for this kernel panic. What do you think? Thanks, Mark
