ureadahead slows down my boot process

[k3lt01]

Binary package hint: ureadahead

Ubuntu, 9.10. i386.

Following the instructions supplied in this thread (All about ureadahead, http://ubuntuforums.org/showthread.php?t=1434502) on Ubuntu forums I am submitting this bug report because ureadahead practically cripples my Acer Extensa 2300 very time it reprofiles. Sometimes I have to do a hard reboot to get the machine going again.

I have, in the past, removed ureadahead in recovery mode to be able to get my laptop to boot and be usable.

Please find attached my bootchart folder also containing ureadahead --dump.txt.

n.b. The 1st bootchart started at 11.46.39and was completed at 11.47.20. The 2nd started at 12.09.00 and finished at 12.42.55 yet only shows 75 seconds of activity. The 3rd bootchart started at 13.11.44 and finished at 13.12.11. The 4th to 6th are just subsequent boots after having to reboot to Karmic because Lucid kept crashing.

If you need any further information don't hesitate to ask.

Hey there, thanks for taking the time to make this report.

Since your problem is during reprofiling, and looking up the spec of your machine, it looks like this is caused by the extremely large memory overhead used for the tracing.

The fix to reduce this should fix your performance problems
