Sandisk 256MB Compact Flash (SDCFH-256) hangs on access (2.4.26)

If there is a better forum for this question, please let me know.

I'm running Debian Sarge/2.4.26-1-i686-smp, trying to access this compact flash using a CF/IDE adapter from ACS (ACS-CF-IDEToCFA). This works fine for every other CF I have tried (128 and 64). I have a number of these parts and they all act the same and they work fine in an
PCMCIA/CF adapter and a USB CF reader. I have set up what I think is
the simplest case, I have run fdisk and mkfs on another machine using the PCMCIA adapter.

When I try to mount the CF it hangs and I start getting "lost interrupt", does anybody have experience or clues that might help me?

I had similar problems with almost the same setup because of devfs, and specially because of devfsd (the devfs deamon).

I suggest you try first to disable the devfsd, and then disbale devfs completely. I think there are very ugly race conditions there that only appear on a "fast enough" CF card.

If you're not using devfs, then I don't know what the problem is... :(
