>Description:
After about two weeks processes accessing the single hard disk (/dev/ad0) hang. ps reports that the process status as D for disk write. The processes can not be killed, and do not finish. If the process is system critical this means that the system crashes, and if it is not, then the system needs to be rebooted before the processes will go away and the disk will become accessible again. When the system comes back up, the drive seems to work fine, and I have not found anything in my logs to show what the cause of the problem might be.
I had been using the drive for swap and backup (via tar), but after several crashes, I moved swap off the drive. Now it just does backups, which do not cause the whole system to crash.
The current drive is the second hard drive I have tried. The first one was also a Maxtor drive (although it was an 80GB drive whereas the new one is 120GB). I assumed that this error was hardware related, so I swapped it out, and brought it home for testing. The manufacturers tests show that there is nothing wrong with the drive. I have not, as yet, been able to try the system with a drive by a different manufacturer.
Because the processes hang in disk writes, I haven't been able to figure out what is causing the crash with any more certainty. Once one process hangs, any other processes that try to access the drive do the same.
>How-To-Repeat:
Use Maxtor drive regularly for a couple weeks for backups. Watch hang, reboot.

The last four lines here are suspicious, but it looks like the system handles it, and goes on working for a couple weeks.
Does anyone know what this problem is?
Thank you, Nathan
