Yes, after getting a clue that this bug could be related to transparent huge pages, I tried to disable CONFIG_TRANSPARENT_HUGEPAGE in 4.17.6 kernel. This results in the same hang I had with 4.14.x kernels. Note that transparent huge pages must be disabled at build time. cmdline op= tion " transparent_hugepage=3Dnever" doesn't change anything. --=20 You are receiving this mail because: You are the assignee for the bug.= --15317361130.4b0d2Bf.25038 Date: Mon, 16 Jul 2018 10:15:13 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://bugs.freedesktop.org/ Auto-Submitted: auto-generated

Yes, after getting a clue that this bug could be related to transparent huge
pages, I tried to disable CONFIG_TRANSPARENT_HUGEPAGE in 4.17.6 kernel. This
results in the same hang I had with 4.14.x kernels.

Note that transparent huge pages must be disabled at build time. cmdline op=
tion
" transparent_hugepage=3Dnever" doesn't change anything.
