Patch to correct problem
I forgot to upload the patch the first time.
Here is a patch for the kernel spec file for 2.6.9-78.0.5: --- kernel-2.6.spec.ORIG-2008-11-06-09:12 2008-09-24 04:16:23.000000000 -0500 +++ kernel-2.6.spec 2008-11-06 09:17:27.000000000 -0600 @@ -27,7 +27,7 @@ # that the kernel isn't the stock distribution kernel, for example by # adding some text to the end of the version number. # -%define release 78.0.5.EL +%define release 78.0.5.EL.LLC %define sublevel 9 %define kversion 2.6.%{sublevel} %define rpmversion 2.6.%{sublevel} @@ -768,6 +768,7 @@ Patch1334: linux-2.6.9-net-sctp-receive-buffer.patch Patch1335: linux-2.6.9-net-sctp.patch Patch1336: linux-2.6.9-netfilter.patch +Patch1337: llc-consolidated.patch # NIC driver updates Patch1350: linux-2.6.9-net-b44-4g4g.patch @@ -3073,6 +3074,8 @@ %patch1335 -p1 # netfilter updates %patch1336 -p1 +# llc consolidated updates +%patch1337 -p1 # NIC driver fixes. # Fix problems with b44 & 4g/4g The patch fixes a BUG in the receiving of fragmented LLC packets.

Brew build: https://brewweb.devel.redhat.com/taskinfo?taskID=1616406 I'm uploading the patched kernel-smp for i686 and x86_64 to: http://michich.fedorapeople.org/bz468890/ It would be nice if you could confirm the bug is fixed there. If you'd prefer other kernel flavours and/or archs, let me know. My next schedule patch day for this host will be 12/29. I will install the new kernel onto the problem host then. Thanks for the work! Created attachment 327673 [details] rhel4: fix BUG() in rx of LLC frames in non-linear skbs [v3] Updated the patch. The difference from the previous version is that this one does not touch the header files. Brew build: https://brewweb.devel.redhat.com/taskinfo?taskID=1622379 I updated the RPMs at http://michich.fedorapeople.org/bz468890/ with this version. This kernel was installed in the problem host on 12/29/2008 at 17:17. If this kernel runs until Friday with out a mishap, I am willing to call this a good patch for the problem. Keith This kernel is working great. I look forward to seeing it in a future update. Keith Committed in 78.27.EL .
