[Bug 262867] [NEW] cd burning causes severe unresponsiveness, and other foul smells

[danielhollocher]

Public bug reported:

I am having lots of trouble burning a cd image.  The default tool makes
my computer INCREDIBLY laggy.  It always lags, and watching the memory,
it looks like it has NO method of caching at all.  I figured the lag
stems from IO wait stemming from dispersed harddrive requests.

This was past experience.

I tried it again to see if it was still happening that way, and it was,
so I canceled and rebooted.

After that I opened up Brasero.  Brasero I think inadvertently caches
because it does a scan of the image before starting again.  Thats a
little better, and works fine for me, since I have 2g of ram, which is
of course plenty to cache a cd image.

At some point, I selected to just run a simulation.  I started it.  I
lost my mouse.  At the time, I thought that my system was just grinding
to a halt, since, it was grinding to a halt.  Later, I realized that my
keyboard was responding to certain keystrokes, and magically, an alt-tab
brought everything back to life.  I could click again!

(Note, I said my keyboard was only responding to certain keystrokes.
Here is what happened.  I happened to have a terminal open.  I learned
that I could type in it.  I have a shortcut key that can open gnome-
terminals, but that wasn't working.  anyway)

After the simulation, Brasero decides to burn the cd automatically,
giving me 10 seconds to cancel.  This frustrated me, since I hadn't
recovered my mouse at the time.

After it finishes recording, it ejects the cd, and then declares that is
going to run a checksum on the cd.  Except, it never pulls the cd back
in.  Great...  I push it back in.

Now, at the time of this writing, it is stuck at %93 of the checksum
process.  (annd...  I'm hitting cancel)

This is all to burn intrepid alpha 4, so I will check that out, and see
if I get better results.  But, on hardy, this is very buggy.
