https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229429 Bug ID: 229429 Summary: FIRST_MSI_INT is too low for large core count systems, panic on boot Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: kevin@your.org As mentioned on the freebsd-current list: https://lists.freebsd.org/pipermail/freebsd-current/2018-April/069203.html FIRST_MSI_INT is too low for some large systems. Without raising this constant, the kernel panics on boot unless MSI is disabled. The original reporter on the mailing list reported success raising it to 512, my system required raising it higher (768 worked). John Baldwin suggested making this a dynamically calculated value. -- You are receiving this mail because: You are the assignee for the bug.
