Re: Demand on WORKING drivers
As someone mentioned about using maxcpus=1 I found taskset X to the second CPU, i.e. taskset -p 2 <pid of X> seems doing the same trick.
The 19 driver survived glxgears and xengine. It usually freezes more or less right away without taskset.
Taskset'ing X to the first CPU would not fix the issue though, I still got the soft freezes.
It looks like a concurrency issue.
Not sure if the workaround would work if we load up both cores.
