System Problems after Kernel Update

[Tucker Hermans <thermans at bowdoin dot edu>]

I just updated my kernel to 2.6.15.1 from 2.6.13.4 because I bought a 
TV-Tuner card and needed to install the drivers, but that is another story.

I rolled the kernel from scratch and installed it using make-kpkg.  I 
then set up the kernel driver with make-kpkg and after dealing with many 
errors occurring because of the transitionary state of fglrx packages in 
Testing I finally reinstalled the binaries from Flavio's site.  I 
restarted X and everything was working fine at first, but then I started 
seeing a marked decrease in certain programs.  A couple times commands 
would not end when run in Konsole, they would finish output but never 
relinquish control; no new prompt would appear.  In addition Firefox 
would not launch after running a couple other programs.

I restarted the computer with the old kernel running and all 
applications worked fine.

I then restarted the computer with the new kernel and things seemed to 
be working but after playing UT 2K4 mozilla stopped working.

I then found a large amount of errors from dmesg, which I do not know 
quite how to deal with. An example follows.
