Add NULL check for it and fallback to no coherence. This will prevent FreeBSD guests from panic on QEMU with the Hyper-V enlightenment hv-synic enabled. For real Hyper-V, both gen1 and gen2 have vmbus_res then they are not affected by this change. 1. https://www.qemu.org/docs/master/system/i386/hyperv.html PR: 274810 Reviewed by: mhorne, emaste, delphij, whu Diagnosed by: mhorne Fixes: e7a9817b8d32 Hyper-V: vmbus: implementat bus_get_dma_ta= g in vmbus Insta-MFC approved by: re (delphij) for 14.0-RC4 Differential Revision: https://reviews.freebsd.org/D42414 sys/dev/hyperv/vmbus/vmbus.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) --=20 You are receiving this mail because: You are the assignee for the bug.=
