[Crash-utility] Linux Banner string missing.

Hey Dave and list, I am the guy who is try to open the 64 bit vmcore dump with 64 bit xen kernel and 32 bit dom0 kernel. Finally, I have received the dom0 kernel with symbols, and I tried to open the vmcore with crash (I patched with your "special patch"). But I have a new problem, the crash utility exits with an error "could not read linux_banner string" <readmem: c034c000, KVADDR, "accessible check", 4, (ROE|Q), ffff82e4> addr: c034c000 paddr: 34c000 cnt: 4 <readmem: c034c000, KVADDR, "readstring characters", 1499, (ROE|Q), ffff72d0> addr: c034c000 paddr: 34c000 cnt: 1499 WARNING: cannot read linux_banner string linux_banner: crash32: boot/System.map-2.6.27.42-0.1.1.xs5.6.0.44.111158xen and vmcore-2010-09-15-19-29-03 do not match! Have you seen these error message before ? and Thanks for any help and suggestion. yours Kevin F LI ps. I attached the log file generated with "-d 31" option.
