Any idea what is means ? The question is if the messages just started to appear on a machine that worked fine before, or if you've just put a new machine into operation and these messages have been there from the beginning. Anyway, having a look at your IDE cables, and probably exchanging them, would be a good thing to try. You didn't mentuion what kind of DMA/PIO mode you are using, but in case you are trying to use anything like UDMA66 and up, you do at least need a well-designed 80-pin IDE cable. You may also want to tell FreeBSD to use PIO for your hard drive in case you are currently using DMA, or the other way round. I recently had a machine with a CD-ROm drive working in PIO mode, and after reading a few megabyte of data from that drive, I'd always get an error message similar to yours. Then, the IDE bus seemed to be totally locked up (both channels), which meant that I had to reset my system or wait for FreeBSD to crash. Interestingly, I could simply use the appropriate sysctls to make my CD-ROM drive use DMA and the problems went away instantly. I still don't know why they were there in the first place, however, as my CD-ROM drive was running standalone as secondary master, with the primary master hard disk being the only other IDE device in my system...
