Bug Description
Binary package hint: sreadahead
Hi,
Sreadahead uses 100 % of the CPU in Karmic. I haven't any SSD disk, and I use ext4.
Is this package installed by default ? Or did I installed it myselft by error ?
When I try to kill it with "Moniteur système 2.27.4" (french), this monitor crash.
What should I join to help ? dmesg ? ls /dev ?
Thanks

I can confirm this bug as I've seen the same behavior. After a fresh boot, when I log in my CPU is running at 100% and the culprit is sreadahead. sreadahead then exits after a minute or so. If you want, you can disable sreadahead by editing the file at /etc/init/ sreadahead. conf and commenting out the line that reads:
exec /sbin/sreadahead -t 0
I did this on my Thinkpad R61 (with a spinning hard drive) and my boot time dropped from 61 seconds to 49 seconds.
