Hello, Using the SLB mutihit injection test module (which I did not write so I do not want to post it here) to verify updates on my 5.3 frankernekernel I found that the kernel crashes with Oops: kernel bad access.
I tested on latest upstream kernel build that I have at hand and the result is te same (minus the message - nothing was logged and the kernel simply rebooted). Since the whole effort to write a real mode MCE handler was supposed to prevent this maybe the SLB injection module should be added to the kernel selftests? Thanks Michal
