Description

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
http://leaf.dragonflybsd.org/~hasso/DL360-verbose-dmesg.txt

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.

Have you tried enabling APIC_IO? It can be better or worse.

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

Hi Hasso,

Would it be possible to test it again with latest master?

Cheers,
