(In reply to Vincenzo Maffione from comment #27)

Hi Vincenzo,

the 11.3 kernel I compiled was standard (ie not my 11.3 / 11.2 Frankenstein)
only change to GENERIC being "device netmap" disablement.

Result was all Q35 network devices: e1000 (em), vmxnet3 (vmx) and rtl8139 (re)
are working.

Now I have isolated problem I have "retired" Frankenstein ;-)

I have also now done equivalent kernel build with 12.0 and get the same result:

So problem in 12.X is consistent with that in 11.3 .

Let me know if there is any other testing or information you would like to do /
provide.

Thanks.

Cheers,

John Hartley.
