[Po-Hsu Lin]

Kernel: 3.2.0-131 Precise (i386)

This is not a regression, as this issue can be reproduced on older kernel.
AMD64 system does not have this issue.

Tested with one of the laptop in the cert lab. (201307-13930)
This issue can be reproduced with 3.2.0-131 but not with 3.2.0-133 in the proposed pocket.

I will leave the bug status as-is, since this is a different node from our normal test pool for regression-testing.

Hi Sam, still an issue?

 very old bug, with no action on it, marking bug as incomplete and will close in 5 days if no update.

[Po-Hsu Lin (cypressyew)]

This issue can be reproduced on that specific system here.

3.2.0-135 on Precise.

But this test is a little bit flaky, the fail rate for this is about 50%
Just like bug 1747630, sometimes they will appear one-by-one, or even failed together, sometimes they will both pass.
