After integrating v4.14.186 commit 5410d158ca2a50 ("usb/ehci-platform:
Set PM runtime as active on resume") into downstream v4.14.x, we started
to consistently experience below panic [1] on every second s2ram of
R-Car H3 Salvator-X Renesas reference board.
After some investigations, we concluded the following:
- the issue does not exist in vanilla v5.8-rc4+
- [bisecting shows that] the panic on v4.14.186 is caused by the lack
of v5.6-rc1 commit 987351e1ea7772 ("phy: core: Add consumer device
link support"). Getting evidence for that is easy. Reverting
987351e1ea7772 in vanilla leads to a similar backtrace [2].
Questions:
- Backporting 987351e1ea7772 ("phy: core: Add consumer device
link support") to v4.14.187 looks challenging enough, so probably not
worth it. Anybody to contradict this?
- Assuming no plans to backport the missing mainline commit to v4.14.x,
should the following three v4.14.186 commits be reverted on v4.14.x?
* baef809ea497a4 ("usb/ohci-platform: Fix a warning when hibernating")
* 9f33eff4958885 ("usb/xhci-plat: Set PM runtime as active on resume")
* 5410d158ca2a50 ("usb/ehci-platform: Set PM runtime as active on resume")

After integrating v4.14.186 commit 5410d158ca2a50 ("usb/ehci-platform:
Set PM runtime as active on resume") into downstream v4.14.x, we started
to consistently experience below panic [1] on every second s2ram of
R-Car H3 Salvator-X Renesas reference board.
After some investigations, we concluded the following:
- the issue does not exist in vanilla v5.8-rc4+
- [bisecting shows that] the panic on v4.14.186 is caused by the lack
of v5.6-rc1 commit 987351e1ea7772 ("phy: core: Add consumer device
link support"). Getting evidence for that is easy. Reverting
987351e1ea7772 in vanilla leads to a similar backtrace [2].
Questions:
- Backporting 987351e1ea7772 ("phy: core: Add consumer device
link support") to v4.14.187 looks challenging enough, so probably not
worth it. Anybody to contradict this?
- Assuming no plans to backport the missing mainline commit to v4.14.x,
should the following three v4.14.186 commits be reverted on v4.14.x?
* baef809ea497a4 ("usb/ohci-platform: Fix a warning when hibernating")
* 9f33eff4958885 ("usb/xhci-plat: Set PM runtime as active on resume")
* 5410d158ca2a50 ("usb/ehci-platform: Set PM runtime as active on resume")
