xhci on Intel Lynx Point still broke

[Doug White]

Hey folks,

Sorry, I'm not subbed to the list, please keep me CC'd on replies.

What's the status on fixing xhci for Intel Lynx Point USB cores? I have several boards with PCHs with this chipset in my lab that have no functional USB if XHCI is enabled in BIOS on -CURRENT with all of the currently committed USB changes. Is there anything I can do to help debug this problem? I found PR 179342 but it seems the issues there are resolved -- would going through the debug procedure there be useful?

The board I am using for testing is:

SuperMicro X10SLM-F -- C226 chipset

I can make this available remotely for testing if needed.

I also have another board with USB issues -- (dis)connects are not handled after boot and the IPMI virtual devices don't attach properly, though USB keyboard works as long as you don't disconnect it:

SuperMicro X9SBAA-F -- Atom S1260 SoC

Thanks very much for any information you can provide.
