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

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

However, with the new card in (no kernel changes), the report appears to be
confused

(btw, how do I generate a report for the 2nd Promise card in the system?)
I've tried many different combinations of the settings in the "Block Devices"
portion of the kernel, but nothing seems to help the situation.
Thanks for the help!

I'm using Linux-2.2.19 with the following patches
- ide.2.2.19.05042001.patch
- linux-2.2.19-reiserfs-3.5.32-patch
- raid-2.2.19-A1
- linux-2.2.19-ow1
The system is a Athlon 800, running on an Abit KA7 with the latest BIOS, 512mb
RAM. This motherboard does not have 66Mhz PCI slots, AFAIK. Both Promise
Ultra100 TX2 cards were put into the exact same PCI slots that the Ultra66's
were removed from.
