I don't know why this happens. What you can do to help debug this is: in config.h.in change: #define DEBUG_EXTREME_ENABLE 0 to #define DEBUG_EXTREME_ENABLE 1 and recompile/reinstall ffado. Then run jackd with verbose level of 8, but definitely capture the output to a file. it will generate a huge amount of debug output. Send me the output log (private mail is ok).

Hi Pieter and anyone else following this discussion. After some additional troubleshooting, I've discovered that either the Expresscard or the Expresscard adapter in my M1210 is the culprit in this problem. I hope it's the card, because at least I can throw that out :) I got desperate and tried out the whole setup in Windows (*sigh*), and it didn't work there either.

Interestingly, the onboard Ricoh firewire works perfectly - it's total failure to work at all in Linux was the start of this quest, so I'm a bit bewildered.

DELL has some bios updates mentioning expresscard support improvements for some laptops, maybe that's the case for you too? In any case, it should be possible to make it work on windows, or work with DELL to make it work. Usually they are less reluctant to help windows users than they are to help Linux users. They always seem to expect that crappy hardware is due to the Linux OS. I'm on rev. A07 and there's an A08, so I'll try to get that to work - seems it has to be installed from the first partition (which Windows isn't) and I've mislaid my documentation for updating from Linux. In any case, using the Saffire via the Expresscard produced really strange timing errors (audio was crackly and slowed down by about 50%, with huge CPU usage) under Windows, however the Ricoh device worked fine. Interestingly, the onboard Ricoh firewire works perfectly - it's total failure to work at all in Linux was the start of this quest, so I'm a bit bewildered. The Ricoh controller is a mistery to me too. I really can't figure out what the exact problem is. In the logs you provided I don't see it though. What version of the Ricoh chip do you have? Greets, Pieter The 8522, IIRC - integrated with SD/MMC reader. Under Linux (both Ubuntu and 64Studio) it crashes out with an Iso Xmit Error 0, as described here http://freebob.sourceforge.net/index.php/FAQ, which seems to be unrecoverable. In Windows it's working fine - which goes against reports I'd seen of the problem being cross-platform...
