I tried majordomo, as on vger, but it didn't work.

Hi,
      
I released a new makedumpfile (version 1.2.0) with vmcoreinfo support.
I updated the patches for linux and kexec-tools.

PATCH SET:
[1/2] [linux-2.6.22] Add vmcoreinfo
  The patch is for linux-2.6.22.
  The patch adds the vmcoreinfo data. Its address and size are output
  to /sys/kernel/vmcoreinfo.

[2/2] [kexec-tools] Pass vmcoreinfo's address and size
  The patch is for kexec-tools-testing-20070330.
  (http://www.kernel.org/pub/linux/kernel/people/horms/kexec-tools/)
  kexec command gets the address and size of the vmcoreinfo data from
  /sys/kernel/vmcoreinfo, and passes them to the second kernel through
  ELF header of /proc/vmcore. When the second kernel is booting, the
  kernel gets them from the ELF header and creates vmcoreinfo's PT_NOTE
  segment into /proc/vmcore.
      
Hi,
When using the vmcoreinfo patches, what tool(s) are available for
analyzing the vmcore (dump) file?  E.g., lkcd or crash or just gdb?

gdb works for me, but I tried to use crash (4.0-4.6 from
http://people.redhat.com/anderson/) and crash complained:

crash: invalid kernel virtual address: 0  type: "cpu_pda entry"

Should crash work, or does it need to be modified?

    

Hi Randy,

Crash should just work. It might broken on latest kernel. Copying it
to crash-utility mailing list. Dave will be able to tell us better.

  
This is on a 2.6.23-rc3 kernel with vmcoreinfo patches and a dump file
with -l 31 (dump level 31, omitting all possible pages).

    

Thanks
Vivek
