freebsd stable - Jul 2006 - graid3 rebuild panic: mb_dtor_pack: ext_size != MCLBYTES

Hi,

I get the below panic when rebuilding a graid3 array. Is this indicative
of a hardware or software problem? Or is some of the data on my array
corrupt and I should just rebuild the array? I searched on google and
didn't find much.

panic: mb_dtor_pack: ext_size != MCLBYTES

Thanks for your time,
Brad

As I can't ever remember seeing that panic before, which is compatible with 
google's conclusion, it's likely this is a sign of kernel memory
corruption.
Whether that is a result of a hardware problem, I can't say.  Is this 
reproduceable?  If so, it could be a graid3 memory corruption problem.  I've

Could you tell me which FreeBSD version do you use?
Can I reproduce it somehow?
