HELP! Passthrough VM kernel panic - PVE 7.3.3

[lxrootard]

Hello

I've experienced this VM crash on a stock pve-manager/7.3-3/c3928077 (running kernel: 5.15.74-1-pve)
[EDIT] there's a more explicit log message in the 2nd crash, see my second message below

The VM worked well for 24h before the crash. The machine is a Celeron MiniPC that I've reinstalled with a fresh proxmox ISO
I have many errors in the logs, I made extensive research but I could'nt find any clue, see attached



It's a debian 10 VM with 4 USB devices in passthrough (2x BT devices 8087:0a2a and 0a12:0001, 1x ZWave controller 0658:0200, 1x RFXCOM 0403:6015).

I suspect the 1st BT device that is an Intel 3165AC Wifi + BT M.2 combo card as it seems its Wifi PCI device is initialized by the host whereas its BT USB device is in passthrough (I just use BT, not the Wifi):

Any suggestions?

Hi there

kernel panic a few hours later:
RIP: 0010:native_smp_send_reschedule+0x34/0x40 RIP: 0010:panic +0x204/0x24a

I made some research it seems related to passthrough
Any Proxmox experts around???

Thks

Just to say that I've disabled IOMMU, wait & see...
