Re: Any O2 R10K patches I should try?

[sgimips NetBSD mailing list - Scott Taylor <sgimips%mrynet.com@localhost>]

R5K O2:

I've tested the r5k O2 X11 now as well, and it is working for me... once
I switched the driver to "crime" as you mentioned recently.

I've done quite a bit of networking traffinc on this r5k with
cvs, ftp and scp, and have now built a kernel as well.

The r5k seems quite stable for me.

I should mention, as I believe someone else pointed out, that My
r5k O2 does not work well with my KVM.  This problem occurs at
power-up under ARCS, and likely is a hardware incompatibility.
Interestingly, the r10k does not exhibit a problem with my KVM.
I will try another r5k O2 and report back if the problem changes.

Will keep an eye out for more test requests on the r5k machines.

R10K O2:

This machine falls over quickly once networking traffic loads.
Off-the-shelf PCI ether cards didn't stabilise it.  As a matter
of fact, it'll fall over in time without networking.
I will have the R10K available should any development there occur.


While I've got tabletop space, any reason for me to check stability
on the various INDYs and Challenge I have?  I recall them being stable
over a year ago.

Cheers,
-scott
