Hi, good morning,

I noticed few bluetooth crashes starting with kernel 6.0.0 release.

With 5.19.x I didn't see this oops and bluetooth works ok.

Kernel oops comes pretty randomly and/or takes some time to occur.

I noticed it happens more frequently when returning from suspend or when trying
to reconnect an already paired earphone headset.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1021905 (kernel=6.0.0,
firmware-linux=20210818, bios=1.19)
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1023076 (kernel=6.0.3,
firmware-linux=20221012, bios=1.19)

This kernel oops is also appearing with 6.0.8 and 6.1-rc3 from debian
experimental + firmware-linux=20221012 and lenovo bios=1.21.

Have a nice day,
Gabriel Francisco
