yes, most of the time, the warning scares people unnecessarily. but if the machine is seeing lots of CRC failures, there should definitely be some prominent messages. perhaps something simple like producing a warning if more than a few of recent IOs have had CRC problems:
int crcState = 0;
on successful IO: crcState >>= 1;
on CRC failure: if (crcState) printk("dang, CRC failed on hda, see http://whatever"); crcState = 1 << 10;
so if >10 IOs succeed between CRC failures, there's no warning. (uh, I guess that would actually be 9, since presumably the retry would succeed...) keeping a global count of CRC failures would be kind of nice, too.
