We can see that we're reading 2048 bytes from port 0x300 and storing
the data in memory location 0x8c1d2071 which causes the OOPS. What's
surprising is that EBP is set to 0x8c1d2071 too which suggests stack
corruption (note that ioread8_rep() is a fastcall so it does not
create a stack frame of its own). What you could do here is add some
printks and watch how dst changes over time to see if you can figure
out a pattern.
Mmm, I do always run with 4K stacks, I guess I'll try that next.
