Hi Sergey, I've heard from a non-official source that some of the early Fresco Logic chips had issues with MSI, so let's try disabling the MSI completely in the xHCI driver. Can you send me the output of `sudo lspci -vvv`? I'll try to make a patch to the xHCI driver to not enable MSI for that Fresco Logic chip once I have that information.
