HCL - Dell XPS 15 9550

In original configuration this laptop suffers from freeze on initial boot when the system attaches the broadcom wifi card to sys-net. To make progress needed to disable the wifi card in BIOS, install was then straightforward.
Used an USB wifi for initial investigation/updates. Needed to assign the USB controller to the sys-net VM and allow non strict pci reset. ThenuUpgraded the fedora23 kernel to the version in unstable repository:
Linux sys-net 4.8.12-12.pvops.qubes.x86_64 #1 SMP Sat Dec 3 19:12:54 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
As there is only one USB controller on this board, this is not a great long-term solution. I then replaced the broadcom wifi card with an Intel 8265 which works very well with the 4.8 v kernel. Generally everything now seems to work well: suspend works, touchpad works well, screen dimming, attaching usb storage. No touchscreen on this model so can't comment on that.

Did your 9550 not come with a Killer 1535? At least that's what is listed on the product page, http://www.dell.com/uk/p/xps-15-9550-laptop/pd?ref=PD_OC

No, it came with DW1830 which is a re-badge of Broadcom. It was bought in the first half of last year.
