Hello,
Out of these two, the first one that is showing "in_atomic():1" seems
more likely to me to be a potential cause of the "scheduling while
atomic" dump.

Does this logic seem reasonable? Are there other debugging techniques I
can use to narrow down the cause for the "scheduling while atomic"?


you could start by giving us pointers to the sources of the two
drivers... without that... how can we look and help?

You can get Intel's source from here:
