 I am using the opencl on CPU, and yesterday I could run my cl code on CPU, and today I found I could not, the err msg is "Internal Error:  as failed". What does this mean?

 The only difference I could figure out is I did an update for the CAL software today, Does this matter?

my sdk version is 2.5,  the platform is A8-3850 and I am using the integrated GPU. The graphic driver version information:
