Comment 11 for bug 1729736

With Linux kernel 4.15.0-041500rc3 from http://kernel.ubuntu.com/~kernel-ppa/mainline, 'lspci' systematically fails to answer, and makes the whole machine freeze after some time.

Following workaround given by Pierre Moreau at https://bugs.freedesktop.org/show_bug.cgi?id=101665 succeeds:
Inside the kernel command line, add options 'acpi_osi=! acpi_osi="Windows 2009"'
