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):

------------------------------------------------------------------------
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.
