In the last rows we see that there are errors in IRQs, then I add showpfexc=1 in the l4linux.cfg, it's the same thing, another thing is what does this mean? If you need more information, I'll show you next time and thanks for your help a second time.

Please add showpfexc=1 to the parameter list. This will show lots more
output and hopefully give more information on what's going on.
