Promise Ultra100 TX2 Issue
Hi all, I have a system running that uses two Promise Ultra66 cards (PDC20262). However, the hard disks are capible of Ultra100 transfer rates. I needed an Ultra66 card for another machine, so I decided to upgrade this one's cards to Ultra100. I purchased a pair of Promise Ultra100 TX2's so that the hard disks could run at their full speed. However, these new cards do not seem to work properly. I upgraded the kernel to 2.2.19 (from 2.2.18) while still using the old cards, just to verify everything worked. After verifing everything came back up alright, I swaped the cards. After the swap, it seemed that everthing would be fine, except that whenever I try to write more than a few bytes to the disk, the system locks hard, no oops or anything else. I did notice that when booting up with the new card, these lines PDC20268: IDE controller on PCI bus 00 dev 78 PDC20268: chipset revision 1 PDC20268: not 100% native mode: will probe irqs later PDC20268: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode. ide2: BM-DMA at 0xb000-0xb007, BIOS settings: hde:pio, hdf:pio ide3: BM-DMA at 0xb008-0xb00f, BIOS settings: hdg:pio, hdh:pio PDC20268: IDE controller on PCI bus 00 dev 88 PDC20268: chipset revision 1 PDC20268: not 100% native mode: will probe irqs later PDC20268: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode. ide4: BM-DMA at 0xc400-0xc407, BIOS settings: hdi:pio, hdj:pio ide5: BM-DMA at 0xc408-0xc40f, BIOS settings: hdk:pio, hdl:pio tell me that the disks are using pio, instead of DMA like they were with the old card. To get more information, I started to look in /proc: With the old, Ultra66 cards in, this is the report from /proc/ide/pdc202xx PDC20262 Chipset. --- General Status - Burst Mode : enabled Host Mode: Normal Bus Clocking : 33 PCI Internal IO pad select: 6 mA Status Polling Period: 15 Interrupt Check Status Polling Delay : 15 --- Primary Channel Secondary Channel - enabled enabled 66 Clocking enabled enabled Mode PCI Mode PCI FIFO Empty FIFO Empty --- drive0 - drive1 drive0 -- drive1 -- DMA enabled:yes yes yes yes DMA Mode: UDMA 4 UDMA 4 UDMA 4UDMA 4 PIO Mode: PIO 4PIO 4 PIO 4PIO 4 However, with the new card in (no kernel changes), the report appears to be confused PDC20268 TX2 Chipset. --- General Status - Burst Mode : enabled Host Mode: Tri-Stated Bus Clocking : 100 External IO pad select: 10 mA Status Polling Period: 15 Interrupt Check Status Polling Delay : 15 --- Primary Channel Secondary Channel - enabled enabled 66 Clocking enabled enabled Mode MASTER Mode MASTER ErrorError --- drive0 - drive1 drive0 -- drive1 -- DMA enabled:yes yes yes yes DMA Mode: PIO--- PIO--- PIO---PIO--- PIO Mode: PIO ?PIO ?
