[Kernel-packages] [Bug 1696852] Re: [SRU][Zesty] arm64: Add support for handling memory corruption

2017-08-16 Thread Kleber Sacilotto de Souza 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
zesty' to 'verification-done-zesty'. If the problem still exists, change
the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1696852] Re: [SRU][Zesty] arm64: Add support for handling memory corruption

2017-06-13 Thread Manoj Iyer 
Patches were applied to Zesty, along with the RAS patch series, and ran
the mce-test hwpoison.

ubuntu@ubuntu:~/testing/mce-test/cases/function/hwpoison$ uname -a 
Linux ubuntu 4.10.0-22-generic #24~lp1696852+mmcorruption.1 SMP Tue Jun 13 
20:53:25 UTC 2017 aarch64 aarch64 aarch64 GNU/Linux


Testing on QDF2400 SDP with mce-test:

ubuntu@ubuntu:~/testing/mce-test/cases/function/hwpoison$ sudo 
./run_hugepage.sh 
[sudo] password for ubuntu: 
hwpoison-inject module is loaded.

***
Pay attention:

This is the functional test for huge page support of HWPoison.
