Description Dave Anderson 2006-05-24 20:29:32 UTC

+++ This bug was initially created as a clone of Bug #193060 +++

Description of problem:
crash utility: vm -p command fails with "pml page" read error

Version-Release number of selected component (if applicable): 
crash 4.0-2.25


How reproducible:
On a x86_64 machine, run the "vm -p" command on any user process.

Steps to Reproduce:


1. On an x86_64 machine, run the crash utility on a vmcore or live system.
2. Enter "vm -p 1", which should dump all pages mapped into PID 1's address space.
3. 
  
Actual results:

crash> vm -p 1
PID: 1      TASK: 1003fe637f0       CPU: 2   COMMAND: "init"
       MM               PGD          RSS    TOTAL_VM
  1003f7404c0       1003da08000      648k    4748k
      VMA           START       END     FLAGS FILE
  1003f748268        400000     409000   1875 /sbin/init
VIRTUAL     PHYSICAL
vm: read error: physical address: 3da08000  type: "pml page"
crash>



Expected results:

A complete dump of all pages mapped into the process address space.

Linda, 

This is the late-breaking bug that needs to be added to the
RHEL3-U8 errata.  Can you set the appropriate fields in motion?

> RHEL3-U8 errata.  Can you set the appropriate fields in motion?

Make that the RHEL4-U4 errata...

Comment 6 Dave Anderson 2006-05-25 20:33:16 UTC

Fix checked in to RHEL4 CVS, crash version 4.0-2.30.
