RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
 RHEL6 install getting a ACPI ERRORS while booting.
  ACPI Error: Field [CDW3] at 96 exceeds Buffer [NULL] size 64 (bits)   
  (20090903/dsopcode-596)
  ACPI Error (psparse-0537): Method parse/execution failed [\_SB_._OSC] (Node 
  f705352c), AE_AML_BUFFER_LIMIT
  ACPI Error (psparse-0537): Method parse/execution failed [\_SB_._OSC] (Node 
  f705352c), AE_AML_BUFFER_LIMIT

Version-Release number of selected component (if applicable):
 2.6.32-44.el6.i686

How reproducible:
 Always

Steps to Reproduce:
 1.Install system i386 2.6.32-44.el6.i686 and boot kernel.

Actual results:
  ACPI Error: Field [CDW3] at 96 exceeds Buffer [NULL] size 64 (bits) 
  (20090903/dsopcode-596)
  ACPI Error (psparse-0537): Method parse/execution failed [\_SB_._OSC] (Node 
  f705352c), AE_AML_BUFFER_LIMIT
  ACPI Error (psparse-0537): Method parse/execution failed [\_SB_._OSC] (Node  
  f705352c), AE_AML_BUFFER_LIMIT

Expected results:
 Failure messages should not be displayed during a normal system boot.

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 3 Matthew Garrett 2010-07-20 14:31:50 UTC 
HP's \\SB._OSC method violates the ACPI spec. \\SB._OSC is documented as taking an 8-byte argument, while the HP firmware is attempting to interpret it as a 12-byte one. HP have ignored the spec for this method and implemented their own as part of the Processor Clocking Control specification. We can't work around this without risking breaking spec-compliant machines. Nothing will actually be broken as a result of this error.
