When I connected HDD to Promise controller, driver doesn't work properly. (4-Stable and 5-Current show different behaviors.) 1) 4.8R and 4-Stable Case When I connect HDD to any(primary master/slave, secondary master/slave) channel of promise controller, system hang(fatal trap 12) after message > ad6: READ command timeout tag=0 serv=0 - resetting workaround: Set hw.ata.ata_dma="0" at loader command line(for CD install), or /boot/loader.conf(for installed one). But it shows very unpleasant perfomance. 2) 5.1R and 5-Current Case When I connected HDD to primary master(alone) or primary master/slave, it works properly. # atacontrol list ATA channel 0: Master: ad0 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 Slave: no device present ATA channel 1: Master: acd0 <HL-DT-ST CD-ROM GCR-8522B/1.00> ATA/ATAPI rev 0 Slave: ad3 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 ATA channel 2: Master: ad4 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 Slave: ad5 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 ATA channel 3: Master: no device present Slave: no device present # atacontrol mode 2 Master = UDMA100 Slave = UDMA100 But when I connect HDD to secondary master(alone) or secondary master/slave, It doesn't work UDMA100. At boot time, driver report below message. > ad6: READ command timeout tag=0 serv=0 - resetting > ata3: resetting device .. > ata3-slave: ATA identify retries exceeded. > done repeated 3 times and fail back to PIO4 mode. In this case, fatal trap 12 doesn't happened. # atacontrol list ATA channel 0: Master: ad0 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 Slave: no device present ATA channel 1: Master: acd0 <HL-DT-ST CD-ROM GCR-8522B/1.00> ATA/ATAPI rev 0 Slave: ad3 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 ATA channel 2: Master: ad4 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 Slave: ad5 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 ATA channel 3: Master: ad6 <WDC WD2500JB-00EVA0/15.05R15> ATA/ATAPI rev 6 Slave: no device present # atacontrol mode 3 Master = PIO4 Slave = ??? It is odd that secondary master(alone) configuration also show message "ata3-slave: ATA identify retries exceeded.". I convinced it is not hardware/connection/cable problem. (I carefully tested on 4 different machine(4Motherboard/16HDD)). I think kern/50559 is similar problem. >How-To-Repeat: everytime (I test it with 4 different machine with same configuration) >Fix: >Release-Note: >Audit-Trail: >Unformatted:
