--- Comment #17 from espritlibre (espritlibre@yadim.dismail.de) ---
sorry for getting back to this late and the confusion i caused, it's a busy
time... the kernels i use are arch kernel, according to the ArchWiki they are
pretty much vanilla upstream kernel with some patches applied, but for the
current kernel i'm running i see no patches in the PKGBUILD.
i have been observing journal in the and can say that even though i'm booting
without being in flightmode but wifi turned on, sometimes

> kernel: Bluetooth: hci0: Failed to send firmware data (-19)
> kernel: Bluetooth: hci0: sending frame failed (-19)
> kernel: Bluetooth: hci0: FW download error recovery failed (-19)
> kernel: Bluetooth: hci0: sending frame failed (-19)
> kernel: Bluetooth: hci0: Reading supported features failed (-19)
> kernel: Bluetooth: hci0: Error reading debug features
> kernel: Bluetooth: hci0: sending frame failed (-19)
> kernel: Bluetooth: hci0: Failed to read MSFT supported features (-19)

appears, or:

> kernel: Bluetooth: hci0: Failed to send firmware data (-19)
> kernel: Bluetooth: hci0: FW download error recovery failed (-108)
> kernel: Bluetooth: hci0: sending frame failed (-19)
> kernel: Bluetooth: hci0: sending frame failed (-19)
> kernel: Bluetooth: hci0: Reading supported features failed (-19)
> kernel: Bluetooth: hci0: Error reading debug features
> kernel: Bluetooth: hci0: sending frame failed (-19)
> kernel: Bluetooth: hci0: Failed to read MSFT supported features (-19)

i played with bluetooth and the kernel didn't panic.


the last panic i got was 2 days ago and it went like this:
https://0x0.st/H2bz.txt (uploaded for better readability, no javascript needed)

i haven't tried 6.5-rc1, but yesterday i updated to linux-6.4.7.arch1-1. since
this bug is so annoying and they happen at random it's hard for me to bisect
and i'm not confident in saying kernel X is bad or good. i have set up kdump
now, which will automatically dump the crash. i hope this will lead to
something useful, i just booted the system 7-8 times but couldn't trigger a
panic.
