I had a READ_DMA timeout situation which I'm pretty sure was related to a drive problem.
I'm running 5.3-RELEASE-p5 on an older machine (333 MHz AMD K6). The 20 GB hard drive in this system periodically, but only occasionally, gave READ_DMA timeout errors. These errors sometimes cited identical block (LBA) numbers from one time to the next. I tried running the system with the case open, in case it was an overheating problem, but this had no effect. I considered replacing the power supply, but I never got around to doing this. Finally, about a week ago, I copied the entire system to a new hard drive. So far, I haven't had even one READ_DMA error since going to the new hard drive. At least in this one case, it seems fairly certain that the problem has something to do with a particular hard drive. Curiously, I did =not= get any READ_DMA errors while I was making a full backup of the old drive in preparation for copying the data onto the new drive.
