nm.  Found ksymmoops 0.6.  On another note, anyone know why the patches in
it for a more usaeable oops log aren't in vger/samba?

I assume you mean linux/scripts/ksymoops.cc, a package that does similar
and works on PPC can be got from ftp://ftp.ocs.com.au/pub/ksymoops.tar.gz

Yeah, found that a bit later on.  Ever pass on the patch for more detailed
oops to Cort/Paul?

(CC'd to Cort and Paul)

its the same Instruction DUMP from the sparc code.
I've found it useful in finding out where modules fsck up.

mousemode

[Louis Kowolowski]

how do you change/force mousemode to a different setting?
i've attempted to use mousemode 15 4 but it tells me that the current setting
is 1, attempts to change it to 4, and leaves it at 1...  any ideas?
thanks

Are you in root? With a multibutton mouse attached? I think there's a
mousemode switch that lists all availible adb devices - you might want to
check that.

The first number is the ADB device ID.  Try different ones (0-15) for it.
I'd recommend starting at 14 and going down until you find a device that
changes.

ksymoops

[Iain Sandoe]

Hi list,

A couple of us are experiencing some trouble with the latest ksymoops
(2.3.3/4).

It says that the symbols mismatch between /proc/ksyms and the System.map.

any ideas what is wrong?
do we need a different version of ksyslogd?

I'm using (I believe) the latest modutils & binutils.

Iain.

 Hi all
 
 We are using a Embedded Planet 8260 board with Embedded linux loaded in it. The target processor is MPC 8260. We need a kysmoops (rpm) for debugging oops messages in kernel.
 Can anyone suggest the link or how can i install kysmoops for Embedded Planet 8260 board with Embedded linux? 
 
 Regards
 Jay
