I am still having problems with my ECS P6VEM2 system.  While I have gotten
the system to boot by using netbsd-current instead of netbsd-1.6, I get
memory errors.  Specifically, this box is used as a router.  When I boot up
the system and do a "ipnat -l" to list active sessions, i see a couple of
normal nat mappings and then i see a few "kmemcpy: bad address at 0xnnnnnn"
errors.  After about 24 hours, this system does not do NAT at all, most
likely because the memory is totally trashed that it uses for connection
tracking.

I am pretty convinced this is a compatibility problem.  While I cannot swap
the processor (it's soldered onto the motherboard) I have swapped the RAM
with known working ECC registered RAM.  It didn't help at all.  Here are
the specs on my machine:

Via C3 733 Mhz
Motherboard:  ECS P6VEM2
VT8601A North bridge
VT82C686B South bridge

This box has worked without a hiccup under linux (although with some weird
boot-time messages).  This box does seem to have definite memory problems
under NetBSD (as described above).  I have also upgraded the BIOS to the
latest version (1.1b) to see if that helps.

I am including a dmesg capture of my system, as well as a similar dmesg
capture of the same system running linux (so you can see those weird error
messages).  If anyone has gotten this system to work on a VT8601A North
bridge PLEASE let me know.  Laine, I noticed your system runs on a VT8604
North bridge, so i'm guessing that's why your system works.  I wish there
were more tests I could run on this system, but the only extra cards I have
attached to this system are 3 Intel PRO100/S ethernet adapters and the
processor is soldered in.

If anyone can help at all, or would like to know more information, please
contact me.  Thanks


Greg
