It depends what you mean by hanging. Usually if a drive is stuck trying to read a bad sector it will take quite a while before it gives up, and during that period all disk access is stalled. The kernel normally retries several times as well. If a bunch of applications are needing to access the disk, they'll appear to be hung up during this process. > > > On Mon, Jun 28, 2010 at 5:02 PM, Jeff Garzik wrote: >> On 06/28/2010 03:38 AM, Simon Li wrote: >>> >>> May 25 15:55:06 shctc-xq-ems22-me18 kernel: ata3: status=0x25 { >>> DeviceFault CorrectedError Error } >> >>> May 25 15:59:59 shctc-xq-ems22-me18 kernel: ata3: status=0x25 { >>> DeviceFault CorrectedError Error } >> >>> Jun 2 10:54:06 shctc-xm-ems21-me18 kernel: ata2: status=0x25 { >>> DeviceFault CorrectedError Error } >> >>> Jun 2 10:54:08 shctc-xm-ems21-me18 kernel: ata2: status=0x25 { >>> DeviceFault CorrectedError Error } >> >>> Jun 2 10:54:18 shctc-xm-ems21-me18 kernel: ata2: status=0x25 { >>> DeviceFault CorrectedError Error } >> >> Your hardware is returning errors, which libata is dutifully reporting... >> >> Jeff >> >> >> > -- > To unsubscribe from this list: send the line "unsubscribe linux-ide" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
