You need to reserve ST-RAM for use by late initializing drivers - stram_pool=512k would be a good start. Not sure this works with only 4MB of ST-RAM though. > But there's also this further up the boot log. > > Ignoring memory chunk at 0x0:0x400000 before the first chunk > Fix your bootloader or use a memfile to make use of this area! > > I tried a memfile, but that just produces the same message. Looks like your kernel gets placed in TT-RAM (because of size?) and hence TT-RAM is listed as the first memory chunk. I don't think ataboot supports a memfile, so it remains the first chunk? I've tried to play around with the MM init code to circumvent this in the past, to no avail. I think memory chunks have to be listed in strict order for MM init to work. I don't think reordering the memory chunk list once the kernel has started will work, so implementing the memfile option in ataboot may be necessary.
