I've been having a series of reboots, and hangs (with and without the ability 
to ALT-Fn to other screens) even since the recent vm fixes (which reduced the 
number of hangs/reboots dramatically!), and finally setup my system for kernel
debugging so that I can get some info to John.  (Sorry, no dump yet, but I did
have the presence of mind to copy down the panic string and stack trace).  

Setup: 8MB Pentium, Digital Starion PC (noname MoBo, Phoenix BIOS, *NO* L2 
cache), Acculogic SCSI cntrl (ncr53c825), Seagate 1GB Hawk, kernel from 
current as of Monday 7PM ('cause I needed the recent DDB commits to build a 
debugging kernel :-).  

Just running ``make world'' and then after a few hours: 

PANIC: vm_page_free: wire count > 1 (3)panic: vm_page_free: invalid wire count

trace:

	_panic
	_vm_page_free + 0x1bd
	_vm_object_terminate + 0x125
	_vm_object_deallocate +0x1a3
	_pager_cache + 0x2a
	_vm_object_trim + 0x5d
	_vm_object_deallocate + 0x168
	_vn_vmio_close + 0x30
	_vn_close + 0x4c
	_vn_closefile + 0x19
	_closef + 0x12c
	_close + 0x83
	_syscall+ 0x195
	_Xsyscal + 0x35
	---- syscal 6 eip = 0x8064ac5, ebp = 0xefbfbecc


I'm running make world today and will check system tonight.  If in debug mode, 
will get a dump this time.  Sorry.  


Thanks!
