           Summary: Strange behaviour SD-->IDE(PATA) converter
           Product: IO/Storage
           Version: 2.5
    Kernel Version: 3.8
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: IDE
        AssignedTo: io_ide@kernel-bugs.osdl.org
        ReportedBy: forest76@gmail.com
        Regression: No


Hi, last time I bought SD-->IDE converter (on fc1306t chipset) to my Vaio
pcg-v505cp notebook (pentium M on Intel 855 chipset). After connected it (with
32G Medion SD class 6 SD card) and instaled ArchLinux distribution, I checked
out disk performance.

Dmesg seem to be fine (on my previously CF-->IDE adapter with 16G 233x CF card,
looks similar and everything working fine):

but hdparm v9.43 (hdparm -i /dev/sda) show no selected current active mode:

 * signifies the current active mode

------------------------------------------------------------------------

and disk performance is low (buffered disk reads about 9M/s due to hdparm
measurement). Moreover I can't get any information about DMA mode. (hdparm -v
/dev/sda don't display dma field at all). In normal desktop works I see
significant degrees in compare to CF-->IDE converter.

When I tested this configuration DOS lowlevel program it show me excelent read
performance (about 35M/s), so I preclude hardware or compability problems.


Greetings, and sorry for english grammar mistakes.
