[Kernel-packages] [Bug 1708130] Re: ISST-LTE: Ubuntu16.04.03: PowerNV: 'ppc64_cpu' commands hangs while changing SMT value with Leaf IO and BASE tests

2018-01-16 Thread Manoj Iyer 
The 4.10 kernel was replaced with 4.13 linux-hwe, please retest with
4.13 (Artful release) and reopen this bug if you are able to reproduce
it. Zesty has reached end of life so please retest with Artful/Bionic.

** Changed in: linux (Ubuntu)

[Kernel-packages] [Bug 1708130] Re: ISST-LTE: Ubuntu16.04.03: PowerNV: 'ppc64_cpu' commands hangs while changing SMT value with Leaf IO and BASE tests

2017-08-22 Thread Joseph Salisbury 
Thanks for the update and being willing to perform the SRU.  It's best
to wait for the testing results like you say.

Thanks,

Joe

@Mauricio,

Do you plan on submitting an SRU request to the Ubuntu kernel team
mailing list once testing is verified by Indira?
