>Description:
FreeBSD Crashes on heavy IO Load. Its not reproducable, but it 
crashes very often (about 2-3 times a day) 

I have a crashdump from a kernel with debugginformation. 

http://mimas.ze.tum.de/~estartu/info.1
http://mimas.ze.tum.de/~estartu/vmcore.1.bz2
http://mimas.ze.tum.de/~estartu/kernel.bz2

The core is about 100kb compressed and 1Gig decompressed. 

Here is the dmesg from the crash that produced this core file

I have two identical computers with the same problem. Both of them 
are running well under linux. The Hardware is new. 

>How-To-Repeat:
Don't know exactly. The probability of a crash grows with the IO load.
