2018-11-29 Thread Po-Hsu Lin
Retested on both entei and baltar,
passed on entei but still failing on balter (with the whole test suite)

Log for balter:
https://pastebin.ubuntu.com/p/82NXmVYS93/

I will give it another shot on balter.

[Kernel-packages] [Bug 1805778] Re: ubuntu_vfat_stress failed again with P8/P9 Bionic

2018-11-29 Thread Colin Ian King
Sam, can this be retested, I think we were getting into dirty page write
amplification because of using vfat on a tmpfs backing store file. I've
reworked the test now to use bog standard vfat on a loopbacked file.

Fix committed: http://kernel.ubuntu.com/git/ubuntu/autotest-client-
tests.git/commit/?id=e39a7d03a6dbda3039514096737d72150877017b

[Kernel-packages] [Bug 1805778] Re: ubuntu_vfat_stress failed again with P8/P9 Bionic

2018-11-28 Thread Po-Hsu Lin
For the P9 baltar, I can reproduce the stress-ng task blocking issue by
just running the test directly (with Bionic in -released)

Title:
  ubuntu_vfat_stress failed again with P8/P9 Bionic

Status in Stress-ng:
  New
Status in ubuntu-kernel-tests:
  New
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This issue just like bug 1801907, but this time it's passed with P8
  "modoc", failed with P8 "entei" and P9 "baltar"

  I haven't run them directly, this is the result when testing with the
  whole test suite.
