Merged to Linux Git on New Year’s Eve was a fix in the form of a code revert for broken MediaTek WiFi on the in-development Linux 6.19 kernel.
A revert was merged to drop a patch that had been applied back during the Linux 6.19 merge window that inadvertently broken MediaTek MT792x WiFi support.
The problematic commit was just trying to strip whitespace from the build date of firmware in the MT76 driver. Unfortunately, it ended up accidentally breaking WiFi support on the MT792x hardware.
The code caused a kernel panic and firmware loading to fail, in turn causing “dead” WiFi on systems with MT792x wireless. Thus for now the quickest solution was just dropping the botched commit.
This MediaTek MT76 WiFi driver fix will be part of the Linux 6.19-rc4 kernel release due out on Sunday.
