Description
Started Haiku in QEMU with this configuration:
qemu-system-x86_64 -hda haiku-nightly-anyboot.iso -cpu host -accel kvm -m 4G -machine q35 -usbdevice tablet
The thread if_config_tqg_0 from the kernel team uses 100% CPU and network switches to "no link"
Removing the "-machine q35" avoids the problem.

Yes, confirmed. With q35 the network controller is 8086:10D3. With "-nic model=e1000" it switches to 8086:100E and the problem disappears.

See TracTickets
for help on using tickets.
Please check whether this produces an "e1000" or "e1000e" class device. If the latter, please use the appropriate flags (probably
-nic e1000
) to see if switching to an "e1000" device fixes the problem.
