panic with heavy writing on md device

Hello,

I got a panic while doing a lot of IO on a md device.
I attached a gdb backtrace of the kernelcore and a dmesg output.

It happened while untarring a 30 MB tar on the background (&) and
traversing this new directory in the meantime.

uname -a
FreeBSD guido.thuis.klop.ws 5.2-CURRENT FreeBSD 5.2-CURRENT #1: Fri Jun 25  
04:03:35 CEST 2004      
root_at_guido.thuis.klop.ws:/usr/obj/usr/src/sys/GUIDO  i386

On the same time I was playing music with mpg123, but that doesn't make  
use of the md device.

I have had this more and always while doing a lot of IO on the md device.

Is there more info you need?

Greetings,

Ronald.
