            Bug ID: 258136
           Summary: panic on boot under ARM64 Parallels, unless set to
                    Other
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs_at_FreeBSD.org
          Reporter: trasz_at_FreeBSD.org

When trying to boot FreeBSD 14-CURRENT under Parallels running on M1 Macbook,
it panics like this (hand-transcribed):

gicv2m0: <ARM Generic Interrupt Controller MSI/MSIX> mem 0x2250000-0x2250ff on
gic0
panic: arm_gic_reserve_msi_range: MSI interrupt 64 already has a handler

The workaround is to set the virtual machine type to "Other"; the above happens
when set to Windows or Linux.

One curious difference between dmesg output in working/not working case is this
line:

gic0: pn 0x0, arch 0x2, rev 0x0, implementer 0x0 irqs 128

It appears when it works (VM type set to Other); it does not appear when it
panics.
