<br>
By default, the kernel attempts to detect and disable unhandled<br>
interrupt sources because they can cause problems with the<br>
responsiveness of the rest of the kernel if left unchecked.<br>
This option will disable this logic.<br>
<br>
just for curiosity, is this option removed in the latest <a href="http://2.6.26.5" target="_blank">2.6.26.5</a> kernel ? because i experimented with compiling a custom kernel and did not ever receive the message . anyway i am running centos without any problem now and i am glad about it.<br>
<br>
Replace the hardware, get better quality stuff. Since this<br>
is USB, get a PCI USB expansion board see if that helps.<br>
About a year ago I bought a USB 2.0 PCI card for one of<br>
my older systems, was about $20 I think.<br>
<font color="#888888"><br>
</font></blockquote>now that you have mentioned it, i have noticed recently that my desktop motherboard usb port has gone slower. i mean previously i used to get 28-30 MB/s transfer speed with my external usb drive. but now the max i get is 10MB/s . i have tested the external drive on my friend's laptop and to my surprise it transferred with 25MB/s ! is it any indication of any potentially disastrous hardware failure issue ?<br>
