[ltp] linux hangs

[Julien Tane]

Hello,

I have an annoying problem on my T22. Once in a while linux ( redhat 
8.0) just hangs. I cannot do anything ...
And this is quite annoying since I have no other solution but to reboot.

The problem is that I have no clue, on the reason of such an occurence ( 
perhaps it has something to do with the mouse,
 since  every time it occured I had been using it. But I am really not 
sure about it.)

ANYWAY. This is not a bug report. My question is the following.  Is 
there anyway to set the kernel
 for more debugging information. Without having to recompile the kernel. 
( I know I am to lazy).
But I had rather not change a "MORE OR LESS" running system.

I would like to try to find the cause of the problem.
 But it seems I could not find any infos on the reason of the problem 
using the current logs.

For those who might think this might be off topic. I thought this might 
have something to do with the Thinkpad,
 and that there might be other people having the same problem.

Thanks for any comment or help,

Cheers and have fun.

Julien
