The latest RHEL release is 5.11 (September 2014). Second, RHEL5's KVM modules were forked from the upstream kernel around 2009. It hasn't had any features added for at least 5 years. In any case, this bug tracker is only for the upstream kernel. Even if the bug was identified and fixed, you would have to open a support case with Red Hat to get it in the distribution---and you would probably get it only in RHEL7, or at most (quite unlikely) in RHEL6, because RHEL5 only has major security fixes applied at this point in time. Anyway, from comment 4, it looks like RHEL5 doesn't have support for SSE instructions (movdqa in this case) to and from PCI BARs. This is supported in upstream since April 2012 (generic support for SSE came in March 2011, while movdqa was added one year later). -- You are receiving this mail because: You are watching the assignee of the bug.
