Hi, I've just found a crash in usb_stor_get_info (actually usb_inquiry which gets auto-inlined). The cause seems to be that ss->transport is set to the pre-relocation address of usb_stor_BBB_transport. Yet ss->transport_reset is set to the correct relocated address of.
The difference between the two is that usb_stor_BBB_reset is declared static and usb_stor_BBB_transport is not. Changing usb_stor_BBB_transport to a static makes things work but I notice that none of the other transport functions are static either so I'm thinking I haven't actually fixed the problem rather just masked it. I did some poking with a lauterbach and from the disassembly it looks like there is a translation table being used when the function pointers are setup by usb_storage_probe and when declared normally usb_stor_BBB_transport ends up at the end. Everything else has the correct relocated address so I wonder if there is an off-by-one error in whatever creates that table. Does this sound familiar to anyone.
