Later I FOUND that the timeout value was 1000 * 36000s in app and the command could execute 136m. Once I changed back using 36000s, the command could only take 27m. > > Right, 136m.

The test took so much time:-) It did fix my problem. It took about 4-hour to zero the whole 1TB SATA disk as required pattern. I also confirmed the result on LSI HBA SAS 1068E and got succeed. Here was the whole debug process. Tue Dec 4 14:42:42 CST 2007 [USI]: ata pass through(16) cdb: 85 0b 06 00 41 00 00 00 00 00 00 00 00 e0 fd 00 [<unknown opcode>: 85 0b 06 00 41 00 00 00 00 00 00 00 00 e0 fd 00 ] scsi_status=0x0, host_status=0x0, driver_status=0x0 info=0x0 duration=14272004 milliseconds status=0x0 Tue Dec 4 18:40:34 CST 2007 [USI] : Time to Perform Zero Disk on /dev/sdb was 237m52secs No kernel message output during the executing. Still one puzzle to consult with you. As you mentioned, the ATA Pass Thru in SELS10 2.6.16.21-0.8 is "broken". So what is the workable vanilla kernel besides 2.6.23.X? I need to have more choice on distribution. For example 2.6.18.X vanilla kernel with your patch can work?
