More MP problems.

[Matthew Dillon]

:After some googling, I see that dumpdev can be set as a variable in the
:bootloader (this should be added to the help for the "set" command" in
:the loader, imho).  I rebooted, dropped to the bootloader command
:prompt, set that variable to /dev/ad1s2b (my swap device) and rebooted.
:
:When I got to the debug prompt, I ran "panic" to cause a panic.  All I
:got was the following 4 lines repeated over and over and over :-)
:
:panic: assertion: gd->gd_vme_base != NULL in vm_map_entry_kreserve
:mp_lock = 00000003; cpuid = 3; lapci_id = 07000000
:boot() called on cpu#3
:Uptime: 16s
:
:The values change, as does the cpu#, but that's the error.
:
:Am I missing some step in getting this core file?

    Hmm.  This is happening in early boot.  It must be just after init
    is started.

    Maybe we don't have enough zbootinit map entries on startup.  Try
    increasing MAX_MAPENT in vm/vm_map.h from 256 to 512.  See if that
    solves the problem or delays it long enough for the system to get
    a crash dump.
