           Summary: Updated ibt-18-16-1.sfi is bugged, "Invalid exception
                    type 03" kernel spam

           Version: 2.5
          Hardware: AMD
                OS: Linux

ibt-18-16-1.sfi

and now my dmesg is full of:

My hardware is:

Bus 003 Device 002: ID 8087:0025 Intel Corp. Wireless-AC 9260 Bluetooth Adapter

I've also updated from 6.14 to 6.15 but I feel like this is down to firmware.

I've downgraded the firmware and the errors are gone.

It's a clear regression caused by the firmware.

I haven't seen this error once since I downgraded the firmware.

With the new firmware, I received dozens of messages per hour.

Hi Artem S. Tashkinov,

Sai would revert this firmware for now and follow up with firmware team for
further debug.

Thanks,
Kiran
