It does the same thing Brice's fix does. Need to put the

Fixes that problem, now i hit the kernel OOPS at drm initalization. 
Thought i saw a patch somewhere already for that...

2.6.12-rc1-mm2 - ppc32 build fails.

2005-03-24 Thread cliff white 

Error message:

This fails for my config, and also for a defconfig build. 
We're thinking the patch 
"[PATCH] ppc32: PowerQUICC II Pro subarch support" 
( http://seclists.org/lists/linux-kernel/2005/Mar/1661.html )
may have hosed up the config, but haven't got that patch to cleanly revert yet.

Sorry for the delay in response. Recent -bk runs still show this problem, for

Running 2.6.10-ac10 on the STP 1-CPU machines, we don't seem to be able to 
complete
a kernbench run without hitting the OOM-killer. ( kernbench is multiple kernel 
compiles,
of course ) Machine is 800 mhz PIII with 1GB memory. We reduce memory for some 
of the runs.

[OSDL] email gateway for STP available

2005-02-07 Thread Cliff White 

In a somewhat beta. 
We're working on our ease-of-use. 
Release 3.0.19 of STP, available at Sourceforge
(http://sourceforge.net/projects/stp )
and via BK
( bk://developer.osdl.org tag: release_3.0.19 )

adds an email gateway, so you can submit test requests without
the Web. 
I am looking for a few beta testers. 
Grab the kit and email me if you're interested in using.
