2.5.69-mm5 errors in dmesg

Hello,

When booting 2.5.69-mm5 I have two errors showing up
in dmesg, the first is the usb irq handler message below which is listed multiple times at boot:

irq 16: nobody cared!

The second error message is a message from the
aic7xxx driver which I have seen before from some of Justin's updates, I only get this error from my Maxtor(Quantum) Atlas 10k III:

Please cc: me in replies, this is a new address and
I am not subscribed at it yet.

Well darn. Surely usb_hcd_irq() is coded correctly.

Maybe there is something fishy going on in the USB state machinery.

We'll hide these warnings soon, so don't worry about it too much.

Perhaps Justin can comment.

I hope not :(

I don't seem to get those errors here, is the "handlers:" info a -mm only feature?

thanks,

No, the "handlers" diagnostic is present in 2.5.69.
