Did a previous kernel version work?

Bjorn, can you take a look at this PCI output, and tell me if it matters
that the host has bus master and latency 0 when it works and is missing
those properties when it doesn't?
Does the lspci differ when booting the same kernel, or is the lspci from
two different kernels?

Is there anything before that line in the dmesg? Because it seems that
the whole xHCI host gets unregistered, and it would be good to know why.
