The reason I ask is that some values seem to be read correctly but others not. I seem to remember something like that keeping me busy trying to get an Au1100 to run. Also, try a different card, too, I experienced hard lockups with CF cards of one brand that (on an electronic level) seemed to behave badly and cause the system to break. > Reverting "[PATCH] Generic ioremap_page_range: mips conversion" makes it > work again: > http://www.linux-mips.org/git?p=linux.git;a=commitdiff_plain;h=8e087929df88 >4dbb13e383d49d192bdd6928ecbf;hp=62dfb5541a025b47df9405ff0219c7829a97d83b I see one thing that disturbs me a lot in this code (before but even more after this changeset): use of casts in the calls to remap_area_pages or ioremap_page_range. Those typically only serve to hide errors and specifically on the Au1100 (probably also on Au1200) because there the physical addresses are 36 bit while virtual addresses are 32 bit. If there is a truncation going on due to wrong datatypes, these casts will disable the compiler warnings. Apropos, the switching between 32 and 36 bit physical addresses was done via a configuration setting in 2.4, try toggling that one, too, if it still exists.
