Interrupt problem on Sony Vaio BZ11XN

[Gilbert Fernandes <gilbert.fernandes%orange.fr@localhost>]

Hello,

I have just installed NetBSD 5.0.1 on a Vaio Sony BZ11XN laptop and I'm seeing 
a huge number of interrupts.
After an uptime of one hour, ioapic0 pin 19 has produced 187203 interrupts 
(systat vmstat).

The machine seems to work properly, I have been compiling some stuff, but when 
checked with the top command, the first CPU has interrupts ranging from 60 % to 
90 % while CPU2 seems OK and handling most of the compiling work.

When machine is idle, I see about 180 000 interrupts in systat vmstat
First CPU has a constant 50 % interrupt time, while CPU2 is at 99 % idle

I'm running the standard kernel from base installation. The only changes I have 
made is install the /usr/pkgsrc and install screen.

If I check the dmesg the ioapic0 pin 19 is the uhci3. There are several USB but 
only this one seems to be generating so much interrupts it loads to 60 % the 
first CPU.

What should I do ? Report this as a problem of just turn off that ioapic pin 19 
if possible at boot using the kernel configuration tool ?

Here is the dmesg :
