Bu listedeki son yama, Bluetooth'un rastgele kesilmesi sorununu (varsa kamera ve parmak izi tarayıcısının yanı sıra) çözmelidir.
XHCI bugfix henüz ana çekirdeğe uygulanmadı, bu yüzden linux-oem
düzeltmeye sahip tek paketlenmiş Ubuntu çekirdek sürümü.
Bu hata hakkındaki izleme bilgileri için bu cevabın altındaki "Kaynaklar" bölümüne bakın.
Hack: Yeniden Başlatmadan Bluetooth'u Geri Yükle
Bir düzeltmenin genel Ubuntu çekirdeğine aktarılmasını beklemek isterseniz, Bluetooth kesildiğinde bu hack'i çalıştırabilirsiniz.
Dizüstü bilgisayarınızın kamerası, parmak izi okuyucusu ve Bluetooth denetleyicisi bu komutu çalıştırdıktan sonra hızlı bir şekilde yeniden bağlanır (her iki satırda):
echo 1 | sudo tee /sys/bus/pci/devices/0000:00:14.0/remove &&
echo 1 | sudo tee /sys/bus/pci/rescan
Not:0000:00:14.0
İlk komutu çalıştırmadan önce aslında xHCI denetleyicisi olduğundan emin olun . Bu komutla yuvayı bulabilirsiniz:lspci -k | grep -B2 xhci

Bu bir yara bandıdır ve kök nedenini düzeltmez. Hata izleme ve harici tartışma için bu cevabın altındaki "Kaynaklar" bölümüne bakın.
