Comment 11 for bug 523788

I can confirm this behaviour also on a Dell studio 15 laptop without any propietary driver and ATI HD 3450 card, but would also like to share another observation: This bug does not appear when ureadahead is in "data-collection-mode" (so for example after a kernel update) only when it is doing what it is supposed to do - speed up the boot process (at least on my box). That also might be an explanation why people seem to report (in the ubuntuforum) that the bug disappears after some updates.
