https://bugzilla.kernel.org/show_bug.cgi?id=220237 Bug ID: 220237 Summary: Bluetooth: MediaTek MT7925 (0e8d:7925) fails to load firmware with timeout (-110) Product: Drivers Version: 2.5 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: are.mehus@xxxxxxxxxxxxxx Regression: No Created attachment 308259 --> https://bugzilla.kernel.org/attachment.cgi?id=308259&action=edit Output from dmesg log Hello, The MediaTek MT7925 Bluetooth device (ID 0e8d:7925) consistently fails to initialize on my Debian Trixie (Sid) system. The kernel log shows a firmware upload timeout (-110) during the boot process. Key Findings: This is not a recent regression. The issue occurs on the latest experimental kernel (6.15) and also on an older kernel (6.12). This is not a missing firmware issue. I have installed the latest firmware-misc-nonfree package and have also manually updated the firmware files from the master branch of the linux-firmware git repository. This is not a power management issue solvable by parameters. The pcie_aspm=off kernel parameter has no effect on the problem. This is not a BIOS/UEFI configuration issue. Fast Boot and other aggressive PCIe power-saving features have been disabled in the BIOS with no effect. This appears to be a fundamental bug in the kernel driver's handling of this hardware. -- You may reply to this email to add a comment.
