proposed patch
Anton, has this bug been reproduced in RHEL4? Rik, I can't reproduce this bug, because I haven't necessary hardware for it. Bug was blindly cloned due to Pete Zaitcev request. I've dig it up logically throw the sources, and I believe 2.6.9 kernel has exact the same issue. Created attachment 160759 [details]
proposed patch
the same as att#160703, just fixed indentation.
Andrius, the original BZ was for 5.1. When Anton posted the patch to rhkl, Pete Z. suggested that it needs to be fixed in 4.6 as well. Note BTW that the patch is in arch/ia64/lib/swiotlb.c, not megaraid. When the subject of testing the patch came up in rhkl, Anton made the case that this is not necessary because the patch is straight-forward and well understood. Setting devel_ack. This should go in 4.6 as an exception, to avoid system crashes. 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. committed in stream U6 build 60. A test kernel with this patch is available from http://people.redhat.com/~jbaron/rhel4/ 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-2007-0791.html |
