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.

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.

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