Maxtor has a long history of doing broken serial numbers, they even shipped disks with serials like: "M0000000000000000000". Regarding this, the first suspect here is the disk itself. Are the examples with the sata/pata in the bug: /dev/disk |-- by-id | |-- ata-Maxtor_4D080H4_D41S8XWE -> ../../hde /dev/disk |-- by-id | |-- scsi-0ATA_Maxtor_6Y160M0_Linux_ATA-SCSI_simulator -> ../../sdb from the same disk model in a different box, or is it a different disk model? What does: scsi_id -g -p0x80 -x -s /block/sda scsi_id -g -p0x83 -x -s /block/sda print? Any chance to check the failing disk on an interface in pata mode, so you get a hd* entry instead?
