https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188897 John Baldwin <jhb@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhb@FreeBSD.org --- Comment #5 from John Baldwin <jhb@FreeBSD.org> --- I would also need a verbose dmesg (so dmesg from 'boot -v') for both of your PRs. In particular, I need to see what the PCI-PCI bridge driver is doing under the hood to manage its windows. It seems odd to me that your BIOS is assigning prefetchable memory to the memory registers for these devices. One hack would be to force the re(4) driver to use its I/O bar instead of its memory bar (you can set the 'hw.re.prefer_iomap=1' tunable in loader.conf to test this). That would confirm that the issue is with the memory BAR. -- You are receiving this mail because: You are the assignee for the bug.
