SRIPATHI KODI <sripathik.com> - 

Crash shipped with RHEL5.4 (crash 4.0-8.9.1.el5) cannot open MRG1.2 vmcores. I see this error while
trying to open a kdump produced on 2.6.31.4-rt14.27.el5rt kernel:

crash: invalid structure size: x8664_pda
       FILE: x86_64.c  LINE: 584  FUNCTION: x86_64_cpu_pda_init()

I tried the latest version of crash from here: http://people.redhat.com/anderson/crash-4.1.0.tar.gz
and it is able to open the vmcore. Hence we need a newer version of crash to be shipped with MRG1.2.

Comment 1 Clark Williams 2009-11-02 21:59:42 UTC
crash package needs to be updated to deal with MRG 1.2 (2.6.31+) kernels

Comment 2 Dave Anderson 2009-12-16 15:46:09 UTC
crash version 4.1.2-1.el5 (ON_QA for RHEL5.5 crash utility errata) is available:

 /mnt/redhat/brewroot/packages/crash/4.1.2/1.el5

Since MRG1.2 shipped with 2.6.24 based kernels, the crash shipped with RHEL5.4 is perfectly capable of handling the core files. However, this will be needed when 2.6.31 or later real-time kernel ships with MRG1.3. We can verify this once MRG1.3 kernels are available.

Suggest we close as a dup of Bug 57159?

Huh?

Comment 6 Clark Williams 2010-03-29 21:42:41 UTC
That's his IBM BZ instance number. 

(and yeah, I went there first and was confused too. What the heck is 'relust' anyway?)

the RH bz he's referring to is:

https://bugzilla.redhat.com/show_bug.cgi?id=530325

Ok, then yes, by all means this BZ can be closed as a dup of 530325.

Re-opening to mark as a duplicate of LTC BZ 57159 (RH 530325). The solution to each is a new version of crash.

Found following two bugs which are related here -

LTC Bug#55402 (Redhat Bug#517952) :  This bug is for requesting an upgrade to latest version of crash tool to be able to open vmcore from newer kernels.

LTC Bug#57159 (Redhat Bug#530325) :  This bug talks about not able to dump the vmcore. This is now fixed on .33-rt kernel, since we are able to get the vmcore now. Thus this bug should be marked as fixed.

Looking at the above two bugs, this one (bug#57442/Redhat Bug#532024) should be marked duplicate of LTC Bug#55402 (Redhat Bug#517952) instead, since thats the one which requests an upgrade to latest crash in MRG1.3. Doing the same.

Thanks!
