OK, then go back to plan A: test with an Ubuntu 16.04 install and if the IR receiver dies there as well with the newer BIOSes report it to Ubuntu. If it's indeed a BIOS issue they should be able to put a bit more pressure on Intel than a few forum users that can easily be ignored.

Well, it appears that after posting the fact of Ubuntu certification to the Intel Community, they have reconsidered. I've given them some config info - hopefully, they'll pass it on to an engineering team.

Thanks for the update! Fingers crossed they find a solution and this gets fixed soon.

so long,
