I already got a problem report with built-in FMC subsystem, but I couldn't reproduce it. Actually, I use drivers/fmc daily (I'm currently finalizing an ADC driver), but I run the whole subsystem as module; it never happens in that case. Thank you for bisecting, I'll take a deeper look as soon as possible (hopefully today). Meanwhile, please disable FMC or build as modules. /alessandro
