os problems

[John R. Sowden]

syslog.1 entry:   (about 20 of these per second for many minutes-pages 
and pages)

Dec 11 14:52:53 sentry10 kernel: [ 3051.657424] [drm:drm_mode_addfb], 
[FB:42]
Dec 11 14:52:53 sentry10 kernel: [ 3051.657440] 
[drm:radeon_crtc_page_flip], flip-ioctl() cur_fbo = dc5db200, cur_bbo = 
c0063a00

tried system logs from the application/system menu-crashed every time.

I have files called whoopsie in a directory call crash  (neither one 
sounds good to me)

when I ran apt-get autoremove I saw a lot of perl files being removed.

There are many many log files, dating back years, some very large (> 40MB)

I started being concerned when the computer seems to be going slow 
(previous messages).

I wonder if the repeated log entries are what is slowing down the computer.

I also saw, when it was booting that (something failed) after several 
pages of attempts scrolled past the screen.  That is whey I was 
attempting to use the system log menu selection.

Help?
