Thank you for your reply.
Thanks for the report! It is interesting. From your backtrace it looks
like the spin_lock_bh() in sh_dmae_alloc_chan_resources() gets interrupted
by an interrupt on the same channel! I do not understand this, because,
normally no interrupts on DMAC channels occur
the patch provides a workaround for eSDHC to avoid missing the card interrupt
changes since V1
* fix some comments typo
* V2 patch is based on Chris Ball's tree, mmc-next branch

The purpose of these patches is to merge at91_mci and atmel atmel-mci drivers.
