Hi, Bluetooth (Intel, device ID 8087:07dc) recently (one or two weeks) started to repeatedly and frequently fail after a year of flawless operation. I have Home Assistant running as a VM in Proxmox. There has been no Proxmox update in the time it started happening, and it had an uptime of two months.

It does work for hours up to roughly a day after a reboot though! When the failure happens, seemingly only a complete reboot of the Proxmox host gets the BT stack fully up again, which is obviously unacceptable.

I'm on kernel 6.5.11-7-pve, PVE 8.1.3.

Code:
root@pve:~# dmesg | egrep -i "blue"

Any tips? Thanks!
