My slow cards are 1-sector, my
Hi,
anyone figured out where the problem is with OpenBSD & CF?
I got myself a cardbus-CF adapter and tested it, the
performance is pretty poor using two cards that worked
with Linux (couple of years ago though, when I still had those) about
~6MB/s both reading and writing.
The 512M card seeme
Here are some results using the Lexar Professional UDMA 300x CF drives.
My favorite CF<->IDE and CF<->SATA converters are from Addonics
http://www.addonics.com/products/flash_memory_reader/adidecf.asp
Here are some typical boot messages from one of my servers with the
Lexar/Addonics combo:

What I don't understand is why most cards perform very well on FreeBSD, but
fail to perform on OpenBSD...

So I briefly switched the CF cards.

In my reply to Stefan, it's a SanDisk Extreme III (2GB).

Hi list,
I have got an interesting problem here. When I use a CF card on Geode LX-800
board, the performance is extremely low (about 1MB/s for reading). I suppose
it is not a hardware problem: Under windows, the performance of read/writes on
the CF is fine.
This is what I get in dmesg:
