Rewind causing lockups in 12-21 build on rpi3

I’m new to lakka and the various software components within and haven’t been able to see any logging to help diagnose exactly where this issue is happening but it is randomly reproducible.

When playing SNES games the system will randomly lock up if you have the rewind feature enabled. I’ve attempted to restart retroarch with debugging enabled to watch the console logs over SSH, as well as looking in lakka logs but can’t see anything worthwhile.

I’ve been able to play for hours with rewind turned off, and am in the process of testing on non-pi hardware as I believe it might be platform specific.

What is the most useful way to report the issue and send feedback to the teams that would benefit from it?

Find out if it happens with other cores, in which case it’s a RetroArch issue and should be reported at https://github.com/libretro/RetroArch. If it’s only SNES, make an issue at that core’s repo. If it’s RPi-specific, be sure to include that in your issue, as well.

If logs show anything, include them in the issue(s). If not, include instructions for reproducing the issue.
