[re-send now that I'm subscribed] Any help would be appreciated - I have an IA64 vmcore from a RHEL4 system, and crash doesn't like it : # file vmcore vmcore: ELF 64-bit LSB core file IA-64, version 1 (SYSV), SVR4-style, from 'vmlinux' # crash usr__2.6.9-89.EL/lib/debug/lib/modules/2.6.9-89.EL/vmlinux vmcore crash 5.0.6 .. copyright stuff omitted .. GNU gdb (GDB) 7.0 ... WARNING: invalid linux_banner pointer: 8a653075c6c36178 crash: usr__2.6.9-89.EL/lib/debug/lib/modules/2.6.9-89.EL/vmlinux and vmcore do not match! Usage: ... I've tried hacking the 5.0.6 src to avoid the linux_banner check, but it just breaks further down the track : WARNING: boot command line memory limit: 59ab0c85d99b2fa9 crash: ia64_VTOP(b929ee8856a6b891): unexpected region 5 address So I'm stuck. The customer assures me the vmcore is from their 2.6.9-89.EL ia64 system. At the very least it would help if I could extract some or all of the dmesg buffer.

Dave, the vmcore is on an internal Red Hat RHEL4/ia64 system - I can give you access details off-list if you think it will help.
