Prarit, Do you have any update? thanks This bug occurs with below processors on RHEL 7.2: Intel(R) Core(TM) i5-6300U Intel Core i5-6200U Intel(R) Core(TM) i7-6600U Intel Xeon Processor E3-1505M v5 (In reply to garrickyang from comment #4) > Prarit, > Do you have any update? thanks > This bug occurs with below processors on RHEL 7.2: > Intel(R) Core(TM) i5-6300U > Intel Core i5-6200U > Intel(R) Core(TM) i7-6600U > Intel Xeon Processor E3-1505M v5 There are patches in RHEL7 z-stream that should resolve these problems. P. 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 Update the CPUScaling test result with errata kernel-3.10.0-327.3.1.el7: 1) Below processors are PASS: E3-1535M v5 E3-1505M v5 i5-6200U i7-6600U 2) Fail processor: i5-6300U error summary: // User Space (min): Error: cpu0 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz User Space (min): Error: cpu1 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz User Space (min): Error: cpu2 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz User Space (min): Error: cpu3 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz // thanks Joe, Can you help to review the CPU scaling test result with errata kernel-3.10.0-327.10.1.el7.x86_64(http://rhn.redhat.com/errata/RHSA-2016-0185.html) and give your comments? thanks 1) Below processors are PASS: E3-1505M v5 i7-6600U 2) Fail processor: i5-6300U,i5-6200U and E3-1535M v5 // error message for i5-6300U,i5-6200U: User Space (min): Error: cpu0 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz User Space (min): Error: cpu1 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz User Space (min): Error: cpu2 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz User Space (min): Error: cpu3 in package 0 has a measured frequency of 499 MHz vs. a requirement of 400 MHz +- 50 MHz // // error message for E3-1535M v5: User Space (min): Error: cpu0 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu1 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu2 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu3 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu4 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu5 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu6 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz User Space (min): Error: cpu7 in package 0 has a measured frequency of 901 MHz vs. a requirement of 800 MHz +- 50 MHz // Thanks 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.
