Hi,
In any IOKit driver, whenever there is any Data Access Error, we get kernel
panic.
Please let me ask, WHY?
Why do we have kernel panic on data access error?
In Linux this kind of Segmentation faults at kernel level doesn't panic.
Is it the PowerPC 970 architecture or is it the kernel?
I think we can take care this exception, if we can print the whole back
trace on screen.
It is true, that such segmentation fault must not be there in kernel code,
but there should not be panic.
isn't it?
Application or driver thread should be terminated on such exceptions.
Regards,
Parav Pandit
