Comment 366 for bug 1690085

FWIW, after 14 days of silence, I have heard back from "<email address hidden>".

When I last wrote I sent them the URL for this discussion.

"<email address hidden>" tells me:

  Thank you for your patience, I understand that the idle hang freezing
  issue is frustrating.

  Thanks for sharing the Bugzilla link, I have glanced through the
  discussion thread and saw that users that have the Power Supply
  Control option available in the bios confirmed that changing the
  setting has resolved their problem.

  This option is the AMD solution and has been provided to motherboard
  vendor for validation and inclusion in a future BIOS release.

  According to comment 279, a poster with the same motherboard as you,
  has pointed to a discussion where it states that an updated BIOS will
  be made available for your motherboard which contains the Power Supply
  Control Option. https://www.hardwareluxx.de/community/f219/

  Although I cannot confirm the accuracy of this post, you may want to
  check with ASUS directly.

I did ask them what the "Power Supply Control" option actually does, and why.

I have asked again.

Given that the "Power Supply Control" option is "the AMD solution" I assume that AMD are the right people to ask ?

FWIW: ASUS PRIME X370-PRO BIOS 3805 has appeared, with the release note "Improve system performance" -- but that does not have a "Power Supply Control" setting (or at least not in the "Advanced/AMD CBS" menu).
