Hi,
one machine I'm testing NetBSD on feels sort of sluggish, which
is strange because it's got lots of RAM (128GB) and a pair of
Xeon(R) CPU E5-2650 CPUs, for a total of 16 physical cores and 32
with hyperthreading.
It looks like one of the CPUs is using most of its time doing
interrupt processing, "systat vm" often shows * in "Intr" and
I have a constant buzz of 6.3% System CPU:
Proc:r d sCsw Traps SysCal Intr Soft Fault PAGING SWAPPING
1 7557281355 * 64277 in out in out
ops
6.3% Sy 0.0% Us 0.0% Ni 0.1% In 93.6% Idpages

pciide0: using ioapic0 pin 17 for native-PCI interrupt
stest: {10}
pciide0 only has the built-in CD drive, if I see correctly.
Full dmesg attached below.
Any hints about what's going on and how to further diagnose and
eventually cure it?
Regards,
