I assume this is an hardware configuration. Would it be possible to change 16bit access to 32bit in MTD chip while running? I tried to reconfigure PXA bank mode to 32 bit mode: probing no more works, and mmio transfers dont crash any more... So if I understood well, PXA just makes kernel crash if accessing a 16bit mapped zone with 32bits words (quite normal, in fact, but not straightforward for me as I'm learning at the same time ;) As I saw different bug reports/issues on MLs with this kind of thing (PXA kernel crashing while probing mtd), shouldn't a #warning, or a printk just before probing annoucing the issue could be added ?
