Re: mmiotracer hangs the system

[karol herbst]

hi all,

mhhh exactly this commit fixed mmiotrace for me and a few other
nouveau devs on x86_64.

Also the error log doesn't really show a problem inside the tracer?
Maybe it would be helpful to provide full dmesg in the case of error,
just to rule silly things out.

I will try to figure out how that bug could happen at all.

Greetings

Karol
