(In reply to Hans Petter Selasky from comment #169)
Hi HPS,
I came to know about this issue from this mail thread [1]. I went through all
the comments mentioned here and given the comments form both tech-lists and
Gerard Seibert, starting from here [2], I did this analysis:
Mike Karels => Gigabyte MB => GA-X99P-SLI (rev. 1.0)
Gerard Seibert => Dell XPS 8930 => 0T2HR0
tech-lists => Supermincro MB => X9DRE-TF+/X9DR7-TF+
Possible Root Causes:
---------------------
- Having a mix of USB 2.0, USB 3.0 and USB 3.x ?
- Chipsets ?
-# Gigabyte (GA-X99P-SLI (rev. 1.0))
-#- C610: Server and Workstation/X99 Highend Desktop (HEDT)
-# Dell XPS 8930 (0T2HR0, Version: A01)
-#- 200 Series (Including X299 Successor of X99) (HEDT) /Z370 (DT)
-# Supermicro X9DRE-TF+
-#- Intel C602J chipset a variant of C600 (Server and Workstation)/X79
(Predecessor of X99)
-# Supermicro X9DR7-TF+
-#- Intel C602J chipset a variant of C600 (Server and Workstation)/X79
(Predecessor of X99)
>From what I could notice (given my limited experience I have to say), these are
the common details amongst all reported cases so far.
Trying to test the 1st possible root cause (Having a mix of USB 2.0, USB 3.0
and USB 3.x ?), I ran tests on:
Lenovo Thinkpad W540:
---------------------
Chipset: Mobile Intel QM87 Express (having USB 2.0 and USB 3.0)
I tried different USB UEFI Setup Configurations, but I didn't see any of the
errors mentioned.
That lead me to the path that it could be a mix of both Possible Root Causes,
hence I did a bit of research and I've found these 2 machines available for
purchase:
Dell XPS 8920:
--------------
Chipset: Intel Z270

Dell Precision T5810:
---------------------
Chipset: Intel C612

I guess that the Dell XPS 8920 one looks like a better test case, but your
input would be highly appreciated.
Also, I want to take the chance and learn more as I want to contribute to the
FreeBSD project, so it would be great if you can provide me with guidance and
mentorship.
Looking forward to your reply
