4.18rc2 PV console issue with pvshim

[Manuel Bouyer <bouyer@xxxxxxxxxxxxxxx>]

Hello,
while testing 4.18rc2 on NetBSD I ran into an issue with pvshim:
when booting a pv guest under pvshim, I can't send characters to the guest
using the pv console. The console otherwise works fine, I can see the
boot message
The same guest booted as plain PV works fine.

Does anyone else see this ?
