Hi Emmanual, > [ 346.869001] scsi host6: aacraid > [ 346.869500] scsi 6:0:2:0: Direct-Access ASR8885 raid3 V1.0 PQ: 0 > ANSI: 2 > [ 346.869692] sd 6:0:2:0: [sdb] Very big device.

That size is greater than the 64-bit LBA addressing (0x93 539F B000). Can you give the dmesg output from the working kernel? Not quite sure where the extra size came from ... Thanks, -Dave -----------------------------------------
