The patches cause a crash on another system - an Opteron system spontaneous reboots at this point during early bootup:
CPU 0/0x4 -> Node 0 tseg: 00cfe00000 CPU: Physical Processor ID: 0 CPU: Processor Core ID: 0 using C1E aware idle routine AMD Performance Monitoring support detected. ... num counters: 4 ... value mask: 0000000000000000 ... fixed counters: 0 ... counter mask: 000000000000000f ACPI: Core revision 20081204 ftrace: converting mcount calls to 0f 1f 44 00 00 ftrace: allocating 16365 entries in 129 pages Setting APIC routing to physical flat masked ExtINT on CPU#0 ENABLING IO [reboot]
this is the CPU type:
