Could you provide your dmesg to confirm that diagnosis? Yes, that looks right. The first SCSI device found is some sort of backplane that only talks async. and we are told that it refuses to negotiate sync. Remaining devices don't refuse, but end up 'wide asynchronous' anyway. Below is the relevant section from the log when running 2.6.13-rc1, followed by the matching section for 2.6.12.
