Hi folks,
I was trying to use Kernel Function Profiler to figure out why my driver's IRQ handler is taking so much CPU time but to my surprise, whenever I try to trace anything, I get a "Unable to handle kernel paging request at virtual address XXXX" error.
Is anybody else seen that or did I screw up my Kernel config ?
cheers
ps: I have tried tracing a few different drivers and they all trigger the same problem.
