The esr register has the details of Program Interrupt on BookE/4xx cpus,
printing its value is helpful.

With this, it will also print the DSISR on 8xx/6xx so it will print garbage.

8xx/6xx provide the information in SRR1. If you want to proceed, you have to do the same as in ISI: Copy the content of SRR1 into regs->dsisr in the assembly handler in head_book3s_32.S and in the instruction TLB error handler in head_8xx.S

                return true;
        default:
                return false;
