That's softraid and vmd is not likely causing this unless you're writing tons of data suddenly and even then it shouldn't even register as anything crazy high. > I do suspend often but during my expirement with snapshot's kernel I keep > system on AC power to avoid any suspend/hibernate and it had hit it. > > If you can suggest anything that I can do to collect some usefull data when > I hit it next time, I'll be appreciated and do it. > dunno, your system seems to be behaving weird. I don't think vmd/vmm is causing excessive acpi interrupts or softraid overhead though. Those things are pretty much unrelated. The only thing I can suggest is try and see if some specific action causes the problem and try to narrow it down. > -- > wbr, Kirill
