You should report bugs to the linux-usb@vger.kernel.org mailing list
(CC'ed). You can post on the mailing list without subscribing.

This is the new version of the chip, not the old version.

There is no panic. The driver failed because the firmware (BIOS) did
not behave the way it is supposed to.

There is no panic. The driver failed, because the chip has an extended
capability bit set which the driver doesn't recognize.
If you can provide documentation (that is, the datasheet) for this new
chip, I will try to update the driver.

What does "lspci -vv -s 6:00.1" for the new version chip show?

That sounds like a bug in the chip.

That line looks very peculiar. Do you get the same thing for the older
chip version?

That's possible. But then why does it work okay for the earlier version
of the chip?
