I am chasing what I suspect is a firmware error for the Realtek RTL8723AE
device. The symptom is that the RX buffer is corrupted, and I get a kernel panic
due to a bad pointer in an interrupt routine.
I am currently checking that pointer for NULL, which is catching some of the
situations, but I am still getting panics from non-NULL pointers that do not
point to a valid address.
Is there any way to test a pointer for validity that will not crash the system
if it is bad?
Thanks,
Larry
