I am seeing similar error messages.

I tried linux-firmware from git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git & I am seeing the same error. Then, If I create a softlink "board.bin" pointing to "board-2.bin" & updated initramfs. The only differences I am seeing are 1) the third from the last line is gone (missing board.bin) & 2) the error number changes to -110. The issue still persists. Please ask Qualcomm developers to share the linux-firmware ath12k files & logs, when they successfully verified the functionality (Wi-Fi 7 features & successful suspend/resume verification). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2077296 Title: Add more region support of QCOM WiFi WCN7850 Status in HWE Next: Fix Committed Status in linux-firmware package in Ubuntu: Fix Committed Status in linux-firmware source package in Jammy: Fix Committed Status in linux-firmware source package in Noble: Fix Released Status in linux-firmware source package in Oracular: Fix Committed Bug description: [Impact] Qualcomm WiFi chip WCN7850 needs new board-2.bin for more regions.
