Comment 34 for bug 1462614

The bug is not resolved for me.

I had the custom firmware linked in this post installed on my computer. When kernel 3.19.0-26 came along, I could not boot and saw errors in the console from hid_init_xxx about retval being 19 instead of 18.

I deinstalled the custom linux-firmware and installed linux-firmware=1.143.3 from the repo. I could boot, but bluetooth didn't work and in the logs I saw error messages about firmware ar3k/AthrBT_0x11020100.dfu missing.

So I downloaded the two missing firmware files from this bug report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1394368 and put them to /lib/firmware. I could not boot again because of the same error from hid_init_xxx about retval being 19 instead of 18.

My assumption so far is that the latest linux-firmware=1.143.3 still doesn't include AthrBT_0x11020100.dfu and with that package system at least boots. However when this file is present, the kernel 3.19.0-26 doesn't boot. Neither boots the kernel 4.2.0-rc8.
