Hi Yuming --

I'm using your ec patch, plus a DSDT modified using my sbs-cm package
(which accesses the Smart Battery system through the EC address space
handler). Here's what happens to the interrupts when I access the battery:

rhdt@sto ~ $ cat /proc/interrupts

Note that the battery access took over 5 seconds! And note, of course,
the big jump in the acpi interrupt count.

cheers,

Rich
