hda: dma_timer_expiry: dma status == 0x20

[srfeo]

Hi there,

I am running Debian3.1 with kernel 2.6.8-2-386 on a Dell Laptop. I am using it as a remotely accessed always-on server. 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?

Thank you for any help!

srfeo,

I'm having the same problem that you are describing below. Have you gotten any further in your diagnosis? What was your fix? I'm not sure if its a hard drive issue, or a SATA controller (i.e., motherboard) issue, or even a SATA cable issue.

I'm running 2.6.11 kernel on SUSE 9.3, with ReiserFS and a WD 250GB SATA drive.

Please let me know if you've figured out the root cause of your problem and what you did to resolve it.

Thanks.
