https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=247944 Bug ID: 247944 Summary: nvme missing interrupt on ESXi 6.7 PCIe passthrough Product: Base System Version: 12.1-STABLE Hardware: i386 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: freebsd@darkain.com Created attachment 216411 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=216411&action=edit missing interrupt I'm using Intel Optane NVMe drives on a Dell R720 server running vSphere ESXi 6.7 using PCIe passthrough to FreeBSD guests. In my particular case, I'm just trying to boot the amd64.iso installer images. 12.1-RELEASE: crashes due to a bug in the NVMe driver that has since been fixed. 12.1-STABLE 2020-07-09 snapshot: produces the screen shot listed below. console flooded with "nvme0: Missing interrupt" messages and a few other error messages. Having let it run for a length of time, the messages just cycle over and over again in that exact pattern. Never fully boots into the FreeBSD installer. 12.1-STABLE 2020-07-09 snapshot (workaround): pciPassthru0.msiEnabled = "FALSE" setting that value in the .vmx file for the passthrough device allows it to work. so there appears to be some other bug effecting MSI-X interrupts between ESXi and FreeBSD 12.1-STABLE. I've been trying to play around with the info in bug #203874 with no luck either way so far. 11.4-RELEASE and 11.4-STABLE 2020-07-09 snapshot: same as 12.1-STABLE 13.0-CURRENT: no issue at all. works exactly as expected.
