Default crash fails to load compressed RHEL5 vmcore

Hello,

I have this issue with compressed RHEL5 vmcore files, I can't get it to loaded to the crash utility. I don't have this problem with RHEL4 vmcores (diskdump).
The debuginfo kernel exactly matches the kernel version that generated the vmcore


[root@test-fc12 ~]# crash *usr/lib/debug/lib/modules/2.6.18-92.1.10.el5debug/vmlinux /nas01/cores/2.6.18-92.1.10.el5.vmcore


crash 4.0.9-2.fc12

2.6.18-92.1.10.el5debug SMP mod_unload gcc-4.1

running strings on the rhel5 vmcore file:


[root@test-fc12 cores]# strings 2.6.18-92.1.10.el5.vmcore | grep 2.6 | head -2
2X6
2T6(

does makedumpconfig's compression have something to do with this? from kdump.conf on the machine where i got that vmcore:


...
core_collector makedumpfile -c -d31
...

Thank you in advace!


Regards,
Marc
