FreeBSD 6.2 stable crasches when running dump on mounted snapshot.

Tue Jan 16 22:12:28 UTC 2007

Hi there,

When I run dump on a mounted snapshot, my machine panics with the error 
that says the following:

"Fatal double fault"
"Panic: double fault"

I can run games in Windows fine and I run setiathome/boinc most of the 
time in Windows when my computer is locked and I'm at work. No problem 
there. It s no problem to "make buildkernel" and "make buildworld" with 
-j2. It has never crashed because of load as I can remember.

Im running RAID-1 on this machine the hard disc are ad8xy and ad10xy and 
I do mount everything via the RAID array called ar0xy. My motherboard is 
an Asus A8N5X and I'm using the on board S-ATA controller for my hard 
discs.

I have tried and changed my /etc/fstab so that they mount it from either 
ad8xy or ad10xy instead ( root usr var etc..) But that does not still 
help me with the problem.

I would be happy to provide more info if you want to, so please let me 
know it I'm missing some crucial information. Or perhaps if I should try 
another mailing list then this one.

Below here is my kernel config and make.conf.

# not guaranteed to.  Using csh is absurd.  The default is to use sh.

# BDECFLAGS are a set of gcc warning settings that Bruce Evans has suggested
