I just test your patch and the following "backport" of sym_scatter in ncr53c8xx:

=========><=========

And all works fine now for me. Unfortunately I don't have other model (C, D, R, J or K) using the same driver to test it more :(

I don't have any cvs ci access, so if there are no negative feedback can somebody ci.

Thanks in advance,
	Joel

It was introduced in 3.3.

If you want 7300LC scheduling support?
There's a whole raft of bug fixes betweem gcc 3.0.4 and gcc 3.3.3.
But I can understand the reluctance to upgrade.

These are developement kernels. Treat them like "unstable".

This is not forcing anyone to upgrade unless they want to use
*exactly* that config file. It's not reasonable to build "unstable"
kernel debs from "stable" tool chain.

This works, but only if -Werror is passed to gcc as well, otherwise, it
only generates a warning and goes undetected. Without -Werror, the
kernel compile should succeed, as where it died before would be built
with 7100LC this way, though I'm unaware of the effect of mixing gcc
optimizations like this...

Hi folks,

Excellent! Just tried this patch on my C180 and can confirm it works.
I'll give it a spin on the B132L too - but the box is heavily tied up
compiling today.

Thanks for working on this Joel.

James owns this. I'll commit it if he tells me it's ok.

I didn't fully review this patch because of extra white space
changes like this one:

> -	struct scr_tblmove data [MAX_SCATTER];
> +	struct scr_tblmove data[MAX_SCATTER];

Not a reason to reject the patch. but it would be nice
if you submitted white space edits seperately.

cut/paste almost nevery works.
Use an editor which can inline the patch file and sends mail
as plain/text. plain/text attachments work for me though it's
preferable to inline the patch.

thanks,
grant

<..snip..>

Patch works fine on the B132L too :-) As far as I know there wasn't
a problem here before (only Ravens seemed affected), but the patch
certainly didn't break anything! The machine has been constantly
compiling big packages (gnome/gtk/perl etc.) since the reboot,
including downloads from portage, large copies.. so the disk has
been getting a thrashing with no hiccoughs.
