Re: 2.6.16-rc1-mm2

[Ed Tomlinson]

Summarizing all this.  There are two problems here.

1. reserifs4 panics when it gets io errors - I remember this was an issue that
needed to be fixed in the R4 code before it moves to mainline...

2. Why does a drive which is fine with 2.6.15-rc5-mm3, return a -5 with 2.6.16-mm3
and above?  Smart reports no problems with the drive hardware.  What has changed 
in the libata/scsi stacks?

Thanks,
Ed Tomlinson
