Hello! I'am working on Supermicro H8QGI+-F board. It is server motherboard with 4 sockets. I use 4 AMD Opteron 6234 processors (12 cores per proc). When Linux boots, i get some strange "do_IRQ: x.55 No irq handler for vector (irq -1)" messages in dmesg. Does anybody know what problem can cause such messages? And why does messages appears only for 1...10 cores? Original bios doesn't have such one.
Example from dmesg:
