Prarit, Thanks for sharing this information. Can you let me know when the z-streams will be released? thanks
Hello Lenovo, At current I am not seeing when these will be released in a 7.2.z release. At this point it should not block any hardware certifications. If it does please email me directly and I will assist in resolving. Thank You Joe Kachuck

Hello Garrick, Please confirm from your email: ##### I verified the CPUScaling test issue with the errata kernel, and got “PASS” for the below processors. For the rest of processors, I will test them later, thank you *Intel Core i5-6200U *Intel(R) Xeon(R) CPU E3-1535M ###### So was this passing before with the errata: https://rhn.redhat.com/errata/RHSA-2015-2552.html kernel-3.10.0-327.3.1.el7 Now it is failing with the newer kernel? I may have misread the email. I am looking to confirm. Thank You Joe Kachuck
Joe, Yes. The two processors failed with the newer kernel. *Intel Core i5-6200U *Intel(R) Xeon(R) CPU E3-1535M
Hello, This issue should not block certifications with this kbase: https://access.redhat.com/articles/2050733 Please put this kbase in the comments of any servers that may see this issue in HWCert. Thank You Joe Kachuck
