The line is here:
KASSERT((w->limit & ((1ul << w->step) - 1)) == (1ul << w->step) - 1,
("end address is not aligned"));
Can you run kgdb and do 'frame 3' and 'p/x *w'?
Also, can you boot your machine, then do 'sysctl debug.bootverbose=1', insert
the card and record the messages in dmesg when it does? (You can likely get
those out of kgdb.)
