Re: Error handling in LibATA

Thanks all for your recommendations. I'm in the process of installing your patch. Per your requests I've attached copies of lspci, dmesg and two excerpts from the messages file. The messages from libata.msg are from a drive attached to the Promise adapter and ide.msg are from a drive attached to the motherboard secondary IDE. In both cases power was removed during testing.

My system is built with 2.6.15 rc5 and I will let you know my results.

Thanks again,
John

As Alan commented, not sure you are using IDE or libata?
Could you send the boot dmesg?

If you are using libata, maybe the following patch can help.
It checks more bits of drv_stat, so status like 0x00 are returned as error.
