more detail.
i think it's reasonable to suspect that something's going wrong
in user land. there are about 10 different ways to get Eio from
devsd. one is that for writes, sdbio() returns Eio if the block is
not within bounds.
also, at least the 9atom version of the ide (or, sdata, sic) prints this
if an actual ata error occurs
if(drive->status & Err){
qunlock(ctlr);
print("atagenio: %llud:%d\n", lba, drive->count);
[...]
and dumps the ata state to the console if the i/o never returns.
