I.e.: we have two reports from you, one tainted about CD grabbing, and one untainted about some generic IRQ-related issue. Could you please try producing an untainted oops with the word scsi in one of the lines? Maybe you are just causing the drive to try hard reading data that don't exist, and thus deliver the IRQ at unusual time? Is this reproducible on non-SMP kernels? -- Alexander E.
