SubjectRe: 2.6.16-rc1-mm2
Date
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
