And actually the cards from Socket and Brainboxes are these that I don't own. So I've never done any test with these cards and maybe they started to work with 2.6.8-rc1 or so, because there are fixes in the serial subsystem. > Alternatively, if somebody could just recommend a CF card that works in > 2.6, I'll pitch this one in the trash and get on with life. I own an old Com1 card that is working in BCSP mode with the serial_cs driver, but it only works at 115200 baud.
