Hi
On the weekend I've finally made the profile update from 17.1 to 23.0, the last step took more than 24 hours to complete with 2000 packages. Before the migration, I did my usual world update so I was up to date when I did the profile migration.
After the update and profile migration, I rebooted. Everything is fine, expect for one thing: I cannot initiate a bluetooth connection anymore.
I use net-wireless/blueman-2.4.3 and net-wireless/bluez-5.78 and this has been working fine. If I open the applet and double click on my mobile phone (or my Nintendo Switch), then my system was able to connect the these devices and pulseaudio would also add a new audio sink. But now when I do a double click, it tries to connect but eventually I get the error message Connection Failed: br-connection-refused.
dmesg does not show anything when I try to connect and all I see in /var/log/messages is
| Code: |
blueman-applet 22.33.02 INFO RecentConns:113 notify : <Device.Device object at 0x7f45302efd80 (blueman+bluez+Device+Device at 0x560012a81250)> 00000000-0000-0000-0000-000000000000
|
the stderr of blueman-applet shows
| Code: |
blueman-applet 22.33.02 INFO RecentConns:113 notify : <Device.Device object at 0x7f45302efd80 (blueman+bluez+Device+Device at 0x560012a81250)> 00000000-0000-0000-0000-000000000000
|
and I don't get any more information.
However, if I initiate the bluetooth connection from my phone (or from Nintendo Switch), then the connection works and pulseaudio adds the "Loopback from <device>". dmesg still doesn't show anything, but my /var/log/messages says now

If I start playing some sound on my mobile phone, I can hear it from my desktop. Same thing happens with the Nintendo Switch, I can connect when the Nintendo Switch initiates the connection, not the way round. Hence, I don't think that pulseaudio is the problem here either.
I suspected that my problem has to do something with the profile migration or with the new kernel version. When I did the world update, these packages got updated
- gcc from 13.3.1_p20240614 to 13.3.1_p20241025
- sys-kernel/gentoo-sources from 6.6.52 to 6.6.58-r1
After the profile migration, I compiled the kernel and the modules again and created a new initramfs. I decided to reboot my machine and start it with the 6.6.52 kernel that was built before the profile migration and here everything works fine: if I start blueman-applet and double click on my phone, then the connection is established without a problem.
I compiled the kernel 6.6.52 again with the new gcc because I wanted to see whether the GCC update or the profile update are somehow responsible, but even this new build of 6.6.52 works as desired. So neither the profile migration nor GCC seem to be the problem.
It seems that the kernel is the problem. When I upgraded the kernel, I executed make oldconfig and it asked 3 questions for new variables (I used the default values:
| Code: |
Default allocator
> 1. zbud (ZSWAP_ZPOOL_DEFAULT_ZBUD)
2:1 compression allocator (zbud) (ZBUD) [Y/?] y
3:1 compression allocator (z3fold) (DEPRECATED) (Z3FOLD_DEPRECATED) [N/m/y/?] (NEW)
Allow /proc/pid/mem access override
> 1. Traditional /proc/pid/mem behavior (PROC_MEM_ALWAYS_FORCE) (NEW) (default choice)
Compact Type Format generation (CTF) [N/y/?] (NEW)
Compressed Debug information
> 1. Don't compress debug information (DEBUG_INFO_COMPRESSED_NONE)
|
I don't see how any of these config variables could change the behaviour at all.
Does anybody know what is going on? I didn't find any bug reports similar to this in bugs.gentoo.org. Should I create a new bug report?
