Description

2007-11-07 21:45:23 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Caution -- post 2.6.23 changes to drivers/firewire/ exhibit a reference counting bug in fw-sbp2. Some SBP-2 devices will not be unregistered from the SCSI stack when plugged out or switched off. The fix is in the latest pull request to Linus, http://lkml.org/lkml/2007/11/6/391, which has not landed upstream yet. Would be good if we can pull in the ohci 1.0 iso receive bits also, a solid version of which only today got posted upstream and is still pending review. Back-port to the stack as shipped in 5.1 is attached to bug 406871 though. Created attachment 289971 [details]
Proposed patch
in 2.6.18-71.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 in 2.6.18-77.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 included in the RHEL5.2 release notes (under "Tech Preview") is the following
note about FireWire... please advise if any revisions are required:

FireWire
The firewire-sbp2 module is included in this update as a Technology Preview.
This module enables connectivity with FireWire storage devices and scanners.
At present, FireWire does not support the following:
* IPv4
* pcilynx host controllers
* multi-LUN storage devices
* non-exclusive access to storage devices
In addition, the following issues still exist in this version of FireWire:
* a memory leak in the SBP2 driver may cause the machine to become
unresponsive.
* a code in this version does not work properly in big-endian machines.
This could lead to unexpected behavior in PowerPC.

Hi, the RHEL5.2 release notes will be dropped to translation on April 15, 2008, at which point no further additions or revisions will be entertained. a mockup of the RHEL5.2 release notes can be viewed at the following link: http://intranet.corp.redhat.com/ic/intranet/RHEL5u2relnotesmockup.html please use the aforementioned link to verify if your bugzilla is already in the release notes (if it needs to be). each item in the release notes contains a link to its original bug; as such, you can search through the release notes by bug number. Cheers, Don An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2008-0314.html |
