2.6.10-5 Kernel Differences

[Matt Patterson]

Hello all,

I was running the hoary backports 2.6.10-3_k7_smp when i was using 
warty. I had to go to that kernel because it was the only one that didnt 
cause hard freezes whenever i used usb 2.0 devices. The only caveat was 
that that kernel didnt automount inserted usb/cd devices. I upgraded to 
hoary with the 2.6.10-5 kernel and found that those automounting 
features were back in, but I also noticed that speeds copying from a 
cdrom are FAR slower with lower cpu utilization. It also just froze 
solid on me.

2.6.10-5 -> 30% cpu during copy from cd, and slow, drives automount and 
show up on desktop
2.6.10-3 -> 50% cpu during copy from cd, fast copying, drives automount 
but dont show on desktop

Has anyone experienced this slow cdrom performance?

Also, what is it that triggers the display on the desktop, apparently it 
is not the mounting of the drive? Is that the inotify feature in the 
kernel? What is it that triggers the mounting of the drive (independant 
of desktop display)? I preferred it when it didnt mount on its own, like 
it did back in warty.

Thanks,
Matt
