Bug ID: 283215
Summary: PCI passthru of wifi card QCNFA765 results in host
freeze or crash
Product: Base System
Version: 14.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bhyve
Assignee: virtualization@FreeBSD.org
Reporter: quentin.thebault@defenso.fr
I am running 14.2-RELEASE on a Lenovo Thinkpad T14s Gen 4 AMD (21F8).
Wifi card:
ppt0@pci0:1:0:0: class=0x028000 rev=0x01 hdr=0x00 vendor=0x17cb
device=0x1103 subvendor=0x17aa subdevice=0x9309
vendor = 'Qualcomm Technologies, Inc'
device = 'QCNFA765 Wireless Network Adapter'
Trying to passthru this card to Ubuntu 24.04 or Windows 10 VMs results in host
system freeze or crash and reboot when the VM tries to interact with it (i.e.
Ubuntu boot, Windows a few minutes after boot or upon using the "Network reset"
that supposedly reloads all network adapters).
I do not find any interesting logs in /var/log/messages or in /var/crash
although I have dumpdev=AUTO
