Hi,
Can someone who has a mpt(4) device tell me if their interrupt frequency
is as absurd as mine is?
\begin{verbatim}
mckinley% vmstat -i
interrupt total rate
clock 272238 1019
ohci1 1 0
fxp0 347 1
atapci0 4 0
mpt0 8286623314361713943 31036042375886569
mpt1 2314885530819653497 8669983261496829
bge0 2105376 7885
Total 10601508845183745406 39706025637392304
\end{verbatim}
I want to know if this is something specific to ia64 or if it's
more commonly seen. Some dmesg(8) output:

No interrupt sharing. The following snippet is the result of filtering
dmesg(8) with grep(1) on irq:
