Re: [REGRESSION] [BISECTED] Unable to use 3D with Radeon 2100 and UI freezes with Firefox

Hi once again, but things are not good with any kernel past the  
reworked IRQ stuff.

It seems that the radeon thing is just one of the manifestations of  
the problem.

Today, I noticed another bad symptom, when I accidentally booted with  
kernel 3.0 (I have many kernels in GRUB2): I printed a LaTeX document  
with only 2 pages of pure text.  My printer is an inkjet printer  
connected via USB to my computer and it took about 6 minutes to print  
those 2 pages. The printer head moved printing something, then it  
paused a bit, then it printed some more, then it paused some more etc.

I just rebooted with 2.6.38 and the very same document was printed  
in, like, 15 seconds...

So, is there anything that I could do to rectify this situation? I  
can give you loads of dumps from here, as long as you tell me what  
would be useful.


Thanks,
