Hi,

 I am really sorry if this is a wrong group but please help me by
redirecting me to a mailing list where I can take some help.

I have a bluetooth keyboard which has multiple connections in it i.e
it can connect to multiple devices with dedicated buttons.
When i connect to linux (Linux bcvm 6.15.0-bcv #8 SMP PREEMPT_DYNAMIC
Sun Jun  1 09:55:01 BST 2025 x86_64 GNU/Linux  - Debian trixie) it
works really well. However if the keyboard goes to sleep or if I
switch the keyboard to a different device, I get a kernel crash
Attached is the crash dump.

Happy to give any more debug info if needed.
This is 100% reproducible (un)fortunately for me.
