The message is coming from drivers/ide/ide.c and is reported when a new
command is to be sent to the device if the device is not ready.

Looking at the kernel code (I happen to be working from home this week) 
the driver appears to be waiting for either on wither BUSY or DRQ[1].
Have you turned the IDE DMA flag on in the kernel?  If so turn it off
and try again.

I'm assuming that the machine still boots find with the old version of
the kernel.
