...d memory. To get back to the prior behavior > iommu.strict=1 may be set on the kernel command line. Maybe add that it depends on CONFIG_IOMMU_DEFAULT_DMA_{LAZY,STRICT} as well, because I've seen kernel configs that enable either. > > Link: https://lore.kernel.org/lkml/20230802123612.GA6142 at myrica/ > Signed-off-by: Niklas Schnelle <schnelle at linux.ibm.com> > --- > drivers/iommu/virtio-iommu.c | 12 ++++++++++++ > 1 file changed, 12 insertions(+) > > diff --git a/drivers/iommu/virtio-iommu.c b/drivers/iommu/virtio-iommu.c > index fb73dec5b953..1b752649...

...looks familiar. I don't have hardware to test this but I guess QEMU system emulation may be able to reproduce the issue since it has an AMD IOMMU (unmaintained) and igb, I can give that a try.
