https://bugzilla.kernel.org/show_bug.cgi?id=190831 --- Comment #22 from Marcin Kurek <morgoth6@xxxxxxxxx> --- Hmm, the #250451 and #250461 looks like current version of .sfi file and older .ddc file. Anyway just tired with #250481: 873629534cf972411618c6c13aef80f2 ibt-11-5.ddc 413da432ba53076ed31a1dda17a1f43d ibt-11-5.sfi The .sfi file has same md5 sum as file currently in linux-firmware repository and only .ddc is different. And it loads fine: Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014 Bluetooth: hci0: Device revision is 5 Bluetooth: hci0: Secure boot is enabled Bluetooth: hci0: OTP lock is enabled Bluetooth: hci0: API lock is enabled Bluetooth: hci0: Debug lock is disabled Bluetooth: hci0: Minimum firmware build 1 week 10 2014 Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi Bluetooth: hci0: Waiting for firmware download to complete Bluetooth: hci0: Firmware loaded in 1312477 usecs Bluetooth: hci0: Waiting for device to boot Bluetooth: hci0: Device booted in 10720 usecs Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc Bluetooth: hci0: Applying Intel DDC parameters completed I can not see any event mask errors which is nice and for now I had no problem with sudden mouse stops/disconect, but it still feels a bit jumpy and definitely not so smooth as it should be. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
