It seems to run quite well, but sometimes after a few months, I get a "dma_timer_expiry: dma status == 0x20" error the file system (reiserFS) resets itself into readonly mode. I get all sorts of Input/Output errors and I can't even reboot the box. > > Is this showing that the disk is bad? It seems not to be as it is working fine for months before getting the DMA errors. Is there anything I can configure to avoid these problems? Is there a kernel modification, or fstab/hdparm command, or other filesystem that I should use that will prevent the drive going into read-only mode? Have a look at this bug report I filed some time ago. It does look rather similar. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=335538 Unfortunately I never did get a fix on it. That said, the problem doesn't happen very often now - maybe something was changed in the few kernel updates since I last looked at the problem. Best regards, -- George Borisov DXSolutions Ltd
