Hi,
When I used crash based off of a mainline kernel to run kmem, it failed. For your information, the detailed description of the problem is as follows.
Version-Release number of selected component:
# uname -a
Linux hp-rx8640-02.rhts.eng.bos.redhat.com 2.6.39-rc6+ #2 SMP Mon May 9 23:05:14 EDT 2011 ia64 ia64 ia64 GNU/Linux
Steps to Reproduce:
1ãupdate the old kernel to the mainline kernel 2.6.39-rc6+
2ãinstall crash
3ã# crash <where the mainline kernel tree is>/vmlinux
4ãcrash> kmem -s
CACHE NAME OBJSIZE ALLOCATED TOTAL SLABS SSIZE
kmem: invalid structure member offset: slab_list
FILE: memory.c LINE: 9588 FUNCTION: verify_slab_v2()
