Sir, Today I noticed that when ever i insert a mp3usb stick it is giving 
Unlink after no-IRQ?  "
"Controller is probably using the wrong IRQ"

Try booting the kernel with "irqpoll". Example:

 > linux noapic pci=irqroute pci=noacpi acpi=off irqpoll

Check if that helps.

but if i insert an  usbflash stick(without mp3)  It is enumerating and i 
can able to mount the usb and read the content

I wonder why iam getting unlink after no IRQ for some devices and for 
others iam not getting that

Well, I just don't know.
What kernel architecture do you use? ppc or powerpc?
In case you use the former (which is deprecated),
you might want to try the latter.

Please clear my query sir

(-: Please follow my advices:

1. DO NOT remove the mailing list from CC: (and the chance anybody is
    able to help you!)
2. post the output of lspci -vv.

Next step is: contact the guys in the linux-usb mailing list.

Regards,
