I can't tell if it is specific to 2.2.5-BETA, since I exchanged a 2740 with a 3740 then upgraded to 2.2.5-BETA. In the meantime, I am trying to do something by disabled SCBPAGING. Any comment would be greately appreciated. Best regards. --------------------------------------------------------- sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): Target Busy sd8(ahc1:10:0): ABORTED COMMAND asc:4e,0 Overlapped commands attempted field rep laceable unit: 1 , retries:4 sd8(ahc1:10:0): SCB 0x7 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0xe6 SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x27 SSTAT1 = 0xb Ordered Tag queued Ordered Tag sent sd8(ahc1:10:0): SCB 0x7 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0xe6 SEQADDR = 0x6 SCSISEQ = 0x12 SSTAT0 = 0x27 SSTAT1 = 0xb sd8(ahc1:10:0): Queueing an Abort SCB sd8(ahc1:10:0): Abort Message Sent sd8(ahc1:10:0): SCB 7 - Abort Tag Completed. sd8(ahc1:10:0): no longer in timeout ahc1: WARNING no command for scb 0 (cmdcmplt) QOUTCNT == 1 sd9(ahc1:11:0): SCB 0x5 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x6 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Ordered Tag queued Ordered Tag sent sd9(ahc1:11:0): SCB 0x5 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x7 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa sd9(ahc1:11:0): Queueing an Abort SCB sd9(ahc1:11:0): Abort Message Sent sd9(ahc1:11:0): SCB 5 - Abort Tag Completed. sd9(ahc1:11:0): no longer in timeout sd8(ahc1:10:0): data overrun of 16736233 bytes detected in Data-In phase.
