[Crash-utility] crash for 2.6.15 kernel ?

Hello Dave and all,

I tried to use crash 4.0-2.20 on 2.6.15 kernel, but it takes a SIGSEGV. 
I think this is due to kmem_cache_s structure being renamed to 
kmem_cache, as explained in:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2109a2d1b175dfcffbfdac693bdbe4c4ab62f11f

Could you tell me if there exists a crash version that supports 2.6.15, 
and how to get it ?
Thanks in advance.
Xavier.
