From: Rachita Kothiyal 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.
