https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D203874 Mahmoud Al-Qudsi <mqudsi@neosmart.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mqudsi@neosmart.net --- Comment #28 from Mahmoud Al-Qudsi <mqudsi@neosmart.net> --- Hopefully this isn't too late but I know there were some issues caused with pass-through PCI-e devices and MSI-X support under ESX 5.5+, but I cannot f= or the life of me find the issue that I know exists somewhere in bugzilla (eit= her this one or on the FreeNAS one). This is not the issue I was searching for (which is one that I've commented on), but here is a report that was originally filed against a FreeBSD system running under ESX 5.1 (not pre-5.0 as claimed in some of the comments above= ): https://redmine.ixsystems.com/issues/2056 This must have been before the hack was added to pci.c because the fix back then was to globally set hw.pci.enable_msix=3D0 (or else individually black= list the LSI device). I personally ran into interrupt storms with MSI-X enabled under 6.0 and a L= SI 9211-8i a few years back, which is how I first came across this back in the day. Googling for some variation of `esxi, freebsd, mps, interrupt storm, l= si, pass-through, vmware` brings up a lot of relevant results, almost all of wh= ich are post ESX 5.0 I am reminded heavily of Chesterton's fence here and would recommend procee= ding only with extreme caution (and after looking into LSI HBA passthrough configurations and scenarios). --=20 You are receiving this mail because: You are the assignee for the bug.=
