I'm having an issue with the Centrino Advanced-N 6235 module. I'm running Ubuntu Trusty, and I've tried both the 3.13 and 3.16 kernels. Haven't yet tried 3.18. What's weirdest about it is that the module actually works with full functionality on an Advantech AIMB-274 (Q87 chipset) with the described software configuration. However, when I plug the module into either a Gigabyte J1800N or an ASRock IMB-152 (J1900), I get no bluetooth— no hci0 device comes up at all in hciconfig dev or rfkill list.
I'd guess that the 6235 module has WLAN on the pci-e connector portion, and Bluetooth on the USB portion. Check the docs on the board you're plugging it into, and I bet the mini-pcie connector doesn't have the USB side wired up, or it's disabled in(or by) the bios?
My sense is that the 6235 is a very popular module, and low-cost celeron motherboards are also pretty popular, so there must be others who have run into this. Maybe people just don't use bluetooth, or don't expect it to work on Linux? Anyhow, here is a gist with the dmesg boot log and lshw output: https://gist.github.com/mikepurvis/ee7bc8fb85ff7ae64a9d Looks like there's a crash in there related to intel integrated graphics— could this be a cause? This is a headless machine, so disabling graphics completely is on the table, if someone can suggest a good way to go about that. Any other ideas as to what's going on here?
