Hi,

we are working on porting seL4 to the Nvidia Jetson Xavier. The
kernel is booting, but then there are random crashes in user mode
where the cores seem to stop completely within a minute, no crash
output is visible. Our test applications are just doing some
integer number crunching to create load, there are no drivers
involved (besides a bit of UART output).
It looks like this also happened to others, a similar problem was
described in this post:

Did anybody get seL4 userland running stable there?
