>Environment:
FreeBSD 4.6.2 (RELENG_4_6) upgraded from local cvsup-mirror sync'ed the 23rd of August 2002. Now down graded to RELENG_4 (FreeBSD 4.6-STABLE)
>Description:
We were testing FreeBSD 4.6.2 on one of our sandbox machines that was
previously running FBSD4.5. After the cvs and additional make's the
machine now seems to be at tad unstable..

When disk i/o start to run of.. for instance during find / -name *~ it
just dumps out one nice error msg like this: 

Fatal trap 12: page fault while in kernel mode
fault virtual address 	= 0x0
fault code     		= supervisor write, page not present
instruction pointer code = 0x8:0xc0215293
stack pointer		= 0x10:0xfef98c40
frame pointer		= 0x10:0xfef98c74
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor enabled	= interupt enabled, resume, IOPL = 0
current proccess	= 142 (cvs)
interupt mask		= bio
trap number		= 12
panic: Page fault

syncing disk....... lotsa numbers.. then rebooots

I've tested the ram and disks extensively with IBM diagnostics tool, and
didn't find anythig wrong there. (It's an IBM xSeries 342 server btw)

>How-To-Repeat:
cd /usr/ports/security/tripwire && make install (during configuration and file search/hash creation)
or 
find / -name *~
>Fix:
Downgrade to RELENG_4 :(
