as mentioned earlier, not overclocking. (and plus I am running Stable and
WinXP with no stability problems).

I didn't make a backup copy (or mark down the errors) of the bad file or try
rebooting which in retrospect would have been a good idea..sorry--I just
fixed the file and saved it so I could compile some ports--and that worked.
I have an IWILL KK266 motherboard which has a "AMI MegaRaid" controller and a
VIA Apollo KT133A chipset. The FreeBSD drive is primary master ad0 on the
via ide line (both Current and Stable are on the same disk). I have a dvd
drive and a cdrw on the secondary channel. Then 2 harddisks, one each on the
RAID controller (I use the bios to alternate which drives are used for
booting--the RAID or the IDE)
some pertinent parts of my STABLE dmesg:

No, Stable has no problems at all like I see in current. Install never messed
up, no data corruption, no traps, few core dumps (and none like I experienced
in Current). I've been running stable on this current computer since early
in the 4.x series and haven't seen this kinda problem before.

1) Yes it happened with a generic kernel straight off the DP2 install CD.
2) I had the problems directly off DP2 iso image burned cd install, so can
that tell you what you need to know about the cvs date or do you want me to
do more?
3) Yes, I'm at college on a fast connection (though with a limited upload) so
if you need to I can setup an ftp login for you on my computer.
thanks,
Scott
