I have a Lenovo LOQ Essential 15ARP11. This card also reports =E2=80=9C0bda:b853=E2=80=9D and = =E2=80=9Crom_version=3D3=E2=80=9D with the same symptoms described. However, I tried to apply the fix by following the instructions, but unfortunately, I was unable to do so. I get the error =E2=80=9Cerror: rtl8852bd_mp_chip_new.dat not found...=E2=80=9D. I downloaded the Windows B= luetooth driver from Lenovo=E2=80=99s support page for my computer model and followe= d the instructions as stated, but I don=E2=80=99t know why it doesn=E2=80=99t inc= lude the required .dat file. I downloaded this one specifically from my computer=E2=80=99s model page (i= t was the only one available there as well): - Name: Bluetooth Driver (Realtek, Mediatek) - Version: 8852BE_18.4032.0.3008,MT7920_25.20.5.20 - Date: Aug 18, 2026 I also don=E2=80=99t know which other driver might have this necessary .dat= file, since it was mentioned that it=E2=80=99s not something found in just one place or= specific to a single brand, but I=E2=80=99d rather play it safe. So, I=E2=80=99ll be waiting for them to fix this kernel bug. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are the assignee for the bug.=
