The Adeos patch simply forces Kconfig to disable the 32kHz clock,
because with a 32kHz clock source, we would only get a 30us granularity
for timer and clock services, which we find unacceptable. But the option
exists for a vanilla kernel as well.

You should try and disable the 32kHz clock on a vanilla kernel, if you
get the same issue, you should report it to the proper mailing list. If
you do net get it, then you have another issue, such as a edge/level
interrupts issue, and should give us more details such as the contents
of /proc/interrupts.

I also happen to run an OMAP3 based system, and I can mount and write to
an SD card with Xenomai without any problem (it is a 2.6.33 kernel,
tested with I-pipe version 1.16-01 and 1.17-01).
