[PATCH] Fix cdrom being confused on using kdump
I have seen the cdrom drive appearing confused on using kdump on certain
x86_64 systems. During the booting up of the second kernel, the following
message would keep flooding the console, and the booting would not proceed
any further.
hda: cdrom_pc_intr: The drive appears confused (ireason = 0x01)
In this patch, whenever we are hitting a confused state in the interrupt
handler with the DRQ set, we end the request and return ide_stopped. Using
this I dont see the status error.
