To use ARM as an example, the bugs I've seen have mostly been in arch specific
code that does things like page-table manipulation. The chromebook bugs I
was hitting for eg were various kinds of PTE corruption warnings.
ISTR the ia64 & sparc64 bugs it discovered long ago were also due to
things like missing cache flushes, as well as trivial fence-post errors.
