Building kernel-2.6.18-87.el5 emits the following warning: arch/ia64/xen/xenentry.S: Assembler messages: arch/ia64/xen/xenentry.S:128: Warning: Use of 'st4' violates RAW dependency 'DTC' (data) arch/ia64/xen/xenentry.S:128: Warning: Only the first path encountering the conflict is reported arch/ia64/xen/xenentry.S:123: Warning: This is the location of the conflicting usage arch/ia64/xen/xenentry.S:128: Warning: Use of 'st4' violates RAW dependency 'DTR' (data) arch/ia64/xen/xenentry.S:128: Warning: Only the first path encountering the conflict is reported arch/ia64/xen/xenentry.S:123: Warning: This is the location of the conflicting usage This is an error in the assembly code that could result in a fault if the tr is referenced without a prior srlz (or instruction implying srlz). This was fixed in upstream xen over a year ago: http://lists.xensource.com/archives/html/xen-ia64-devel/2007-02/msg00001.html http://xenbits.xensource.com/xen-unstable.hg?rev/0df9dc2f1d03 Version-Release number of selected component (if applicable): 2.6.18-87.el5 (and prior versions)
Created attachment 300073 [details] xen-unstable 0df9dc2f1d03 ported to kernel-2.6.18-87.el5
Changed priority from high to medium since it'll be fixed in 5.3 and while it's important to get it fixed because it would cause a crash if hit this has not been seen by a customer so far so we don't feel that we need to put it in the release notes

There's no real test case except for building and verifying the patch is applied and the warnings are gone, so I built kernel-2.6.18-125 and yes, it looks good. I added PartnerVerified to the keywords.
