Description Dave Anderson 2006-05-24 20:26:47 UTC
Description of problem:
crash utility: vm -p command fails with "pml page" read error

Version-Release number of selected component (if applicable): 
crash 4.0-2.24


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: 10016394000       CPU: 1   COMMAND: "init"
       MM               PGD          RSS    TOTAL_VM
  10016785b00       10016719000      528k    3632k
      VMA           START       END     FLAGS FILE
  10016783d80        400000     408000   1875 /sbin/init
VIRTUAL     PHYSICAL
vm: read error: physical address: 16719000  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?

Comment 2 Linda Wang 2006-05-24 21:03:58 UTC
Request exception, this is a bug was found by developer during unit testing. 
crash utility on x86_64 using arugument "vm -p" fails with a read error.

Comment 3 Linda Wang 2006-05-24 21:28:34 UTC
Also to clarify, this is not a beta blocker. Would be nice if the package
gets pick up by GA.

Comment 5 Dave Anderson 2006-05-25 20:32:06 UTC
Fix checked into RHEL-3 CVS, crash version 4.0-2.29.
