The first patch is the same patch of v3 as is. The following commits fix the issues in the original patch. For details, please check the commit log of each patch. I tested these patches in the following systems: * IBM X3550 M3 * HP ProLiant DL380 Gen9 * HP ProLiant BL480c G1 * Dell PowerEdge R910 * Cisco UCSC-C220-M3S I cc everybody that reported problems with the previous version of this patch so they can retest and confirm their systems work flawlessly.
