Interrupt storm related to SATA DVD device
There is a constant interrupt storm in my HP Proliant DL360 G6 machine which
stops in two cases - if I disconnect the DVD device or mount a CD from it.
Verbose dmesg is available at

Just looking at the dmesg, 16 cores? I thought those 1RU things can only
fit 2xquad core xeons?

These are Nehalem CPUs. They are quad-core, but with 2-way SMT.
4 cores, 2 threads per core => 8 virtual cores per socket.

Worse. The storm is still there, but no CD device found - therefore no
workaround either :).
