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 ?
http://www.linuxtopia.org/online_books/linux_kernel/kernel_configuration/re18.html
By default, the kernel attempts to detect and disable unhandled
interrupt sources because they can cause problems with the
responsiveness of the rest of the kernel if left unchecked.
This option will disable this logic.
just for curiosity, is this option removed in the latest 2.6.26.5 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.
Replace the hardware, get better quality stuff. Since this
is USB, get a PCI USB expansion board see if that helps.
About a year ago I bought a USB 2.0 PCI card for one of
my older systems, was about $20 I think.
