>Description:
5.3 generates dma errors with some Maxtor hard drives when the drive is subject to heavy use.
This has affected four 250GB drives I have tested, all of which work without problem under 4.10.
Errors in /var/log/messages are as follows:
Dec 12 20:06:54 goodparley kernel: ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=185165575
Dec 12 20:06:56 goodparley kernel: ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=185165576
and so on. When fsck is run on the drive, the following output is obtained:
#fsck /dev/ad0s1d

** Last Mounted on /mnt

and so on. This is entirely repeatable.

Then I reinstalled the same machine using 4.10 and could use the disk without problem.
>How-To-Repeat:
Install 5.3 on any machine with an Intel 865 or 845 chipset, install Maxtor 250GB hard drive. It has been entirely consistent.

None.
