I am running Qubes 4.0 on MacBook Mid-2015 (exactly the same model
described here: https://www.qubes-os.org/doc/macbook-troubleshooting/).
The whole system crashes after attaching the Broadcom Wifi adapter to
sys-net VM. This behaviour is described in the troubleshooting article
mentioned above, however the workaround does not work for me.
When sys-net is not running I do:
[root@dom0 ~]# xl pci-assignable-list
0000:0b:00.0
0000:04:00.0
[root@dom0 ~]# lspci | grep 04:00
04:00.0 Network controller: Broadcom Limited BCM43602 802.11ac Wireless
LAN SoC (rev 01)
[root@dom0 ~]# echo 04:00.0 > /sys/bus/pci/drivers/pciback/permissive
[root@dom0 ~]# cat /sys/bus/pci/drivers/pciback/permissive
0000:04:00.0
[root@dom0 ~]# qvm-start sys-net
[root@dom0 ~]# xl pci-attach sys-net 04:00.0
[root@dom0 ~]# xl pci-assignable-list
[root@dom0 ~]#
After this I don't see the wifi card in lspci output of sys-net.
I don't see anything in sys-net's dmesg either.
If I now attach the wifi card using qvm-pci (or GUI) the system will
crash.
Any idea how I can handle it?
Try using these newer steps for permissive mode in 4.0:
https://www.qubes-os.org/doc/assigning-devices/#r40-1. Might help your
Thunderbolt problem too.
Many thanks for your answer.
The new way of managing devices does not help though.
Fails for both WiFi and Thunderbolt Ethernet, ie. WiFi crashes the whole system
and Thunderbolt Ethernet is not handled properly by tg3 driver.
Any other ideas how I can move forward?
I don't have any networking available at the moment... if there was at least
one networking device available I could enjoy the Qubes...
Try changing your sys-net's template to Debian instead. Might be able to
use a USB-Ethernet adapter as well, if there's an external port.
Is it possible that OS updates (dom0 and/or VM) would fix any of these issues?
I mean I run Qubes 4.0 from the ISO and cannot even install any updates because
of the lack of connectivity...
If so, how can I upgrade by downloading relevant packages on other system?
Some have had luck installing and updating Qubes on a spare system, then
moving the entire hard drive. This has its own set of complications
though, if using EFI boot.
