https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235876 --- Comment #9 from John Baldwin <jhb@FreeBSD.org> --- Created attachment 202488 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D202488&action= =3Dedit thunderx2_uart_workaround.patch Here's an untested patch to restrict ignoring the Producer flag to the Cavi= um uarts. I didn't do a full-blown quirk field and set of quirks since we just have one for now. If we ever needed one in the future we could do that (ma= ybe with a table of _HID values and quirk masks), but for now this change would= be sufficient. It's probably best to test this on the ThunderX2 first to make sure it works and then we can see if it fixes the issue on Hyper-V. --=20 You are receiving this mail because: You are the assignee for the bug.=
