Package: src:linux Version: 6.12.88-1 Followup-For: Bug #1136807 X-Debbugs-Cc: [email protected]
This regression hit me after upgrading from kernel 6.12.86-1 to 6.12.88-1. Comparing dmesg before and after, I see that the good kernel says this: [ 8.488662] Bluetooth: hci0: Device setup in 170813 usecs ...where the bad kernel says this: [ 8.691042] Bluetooth: hci0: Failed to send wmt func ctrl (-22) That error message also appears in recent lkml discussions of mainline commit 634a4408c061. If it was backported into 6.12.88 (I haven't checked yet) it could explain the bug we're experiencing. The bad mainline commit is being tracked by regzbot, titled "Bluetooth: btmtk: initialization fails on MediaTek MT7922": https://linux-regtracking.leemhuis.info/regzbot/mainline/
