Yes, see my report in this thread. Full bootlog up to the hang (serial captured) was attached, alongside the kernel config. > and lspci -vvnn Attached below. > the bug reporting needs work, this snippet hasn't the useful info in it. Linus quoted only the relevant portion of my full bugreport. All the other info is in the full mail he quoted.
