Does it find the storage controller (what kind of storage does it use?). For the PASEMI board can you test the attached patch? Also are you using Compact Flash cards on that system? > @All > Could you please also test Christoph's kernel on your PASEMI and NXP > boards? Download: 'git clone git://git.infradead.org/users/hch/misc.git -b > powerpc-dma.4 a' FYI, I've pushed a new powerpc-dma.5 with the various fixes discussed in this thread.
