Hi. I'd just like to second Adi Kriegisch's bug report (and hopefully provide some further clues to the problem)
I can definitely confirm that the problem appears to be triggered by upgrading the kernel. In my case from kernel-image-2.6.8-2-686-smp_2.6.8-12_i386 to kernel-image-2.6.8-2-686-smp_2.6.8-13_i386 Each time smartd touches the drives it generates the following logs Feb 7 20:02:22 flow kernel: scsi: unknown opcode 0x4d Feb 7 20:02:22 flow kernel: scsi: unknown opcode 0x4d Feb 7 20:32:22 flow kernel: scsi: unknown opcode 0x4d Feb 7 20:32:22 flow kernel: scsi: unknown opcode 0x4d This is on a two drive system, one actual scsi and one ide drive. Please note that this bug seems to be suppressing all other output (ie I am not getting temp changes being reported although it seems to be able to do so at least partialy on boot.)
