Hello world! First time posting in the forums but I've been using Gentoo for years now.

I use PlayStation 3 controllers over Bluetooth on my desktop, and I noticed that after a kernel rebuild, I can no longer use them. They try to connect and immediately disconnect again. PlayStation 4 controllers and a Bose speaker still work fine.

I turned on debugging output for Bluez and got this in daemon.log:
Code:

Nothing related to Bluetooth shows up in dmesg.

I don't remember exactly what I did to troubleshoot from that point but it didn't appear to be a problem with bluetoothd. So I tried booting an older kernel, and hey, my controllers work again! So, OK, it's a kernel problem. I'll just rebuild the newer kernel, right?

This is where it gets weird. ANY kernel I build with this system is broken in the same way, doesn't matter if it's newer or older than the known-working one. And I'm absolutely sure the controllers were working on older kernels at the time they were new, just not when I rebuild a similar kernel now. So, OK, there's probably something wrong with my @system packages. This is a testing keyword system, so I'll just reboot into my stable partition and surely that one can build a working kernel, right?

... Well the first thing I did is update the stable system THEN try to update its kernel and now it can't build a working kernel anymore either. By the way, its old kernel still works too.

I think the dates the working kernels were built might be a clue to what's changed since then that might be causing the problem. So between both systems the kernels are:
    4.19.27-gentoo-r1 built April 29, working
    4.19.44-gentoo built May 22, NOT working
    5.1.0-gentoo built May 8, working
    5.1.3-gentoo built May 21, NOT working

I also tried building 5.0.17-gentoo but it didn't work either and I no longer have it installed.

tl;dr ANY kernel I build on up-to-date Gentoo amd64 OR ~amd64 system has a broken Bluetooth stack and PlayStation 3 accessories will connect then immediately disconnect.

If needed I could provide the kconfig but 1) it's cousins to allmodconfig so it's a big paste and 2) I don't think it's relevant since I can use the exact same config from the working kernel to build a broken kernel.

Hi,

Kernel huge regression. Have a look here :

Between May 8 and now, did you switch to GCC 9.1? Try the older one.

Thank you both for replying!

Ant P: I did try an older GCC but it didn't help. And the kernel that worked was also built with GCC 9.1 so I didn't think that was the problem.

netfab: I looked at the pages you linked and ended up applying the RFC patch from the kernel mailing list to =sys-kernel/gentoo-sources-5.1.4 which fixed the problem for that kernel. This is good enough for me until the fix is in a released kernel, so I'll see if I can mark this thread solved.
