Comment 11 for bug 1856387

Hi Anthony,

As you may have found, this commit was landed in bug 1851216 for a possible system hang due to bug 1840239, and since it is a solution backported from v5.3-rc1, and you also stated this can be reproduced in v5.5-rc1, then you may probably want to either 1) try a slightly newer v5.5-rc5 mainline kernel[1], or 2) file a upstream bug in kernel bugzilla[2].
