I know this bug is already closed, but profiling should create a bigger

It sounds like you've booted with "profile" at some point; that will

Seems better with 2.6.27-2:
[EMAIL PROTECTED]:/etc/readahead$ wc -l boot

Hmm... I installed 2.6.27-1 and reprofiled:
[EMAIL PROTECTED]:/etc/readahead$ wc -l boot
2815 boot
[EMAIL PROTECTED]:/etc/readahead$ wc -l desktop
253 desktop
Something hinky is going on with my setup, the version of readahead is
the same.
My root is JFS mounted relatime. /home is on ext3 relati
This does not happen with me, although the readahead version is slightly
different:
[EMAIL PROTECTED]:/etc/readahead$ wc -l boot
838 boot
[EMAIL PROTECTED]:/etc/readahead$ wc -l desktop
253 desktop
[EMAIL PROTECTED]:/etc/readahead$ uname -r
2.6.26-5-generic
[EMAIL PROTECTED]:/etc/readahead$ dpkg
Also experienced this with intrepid with kernel 2.6.26.. with 2.6.27-1.1
it's down to a few seconds.
[EMAIL PROTECTED]:~$ uname -r
2.6.27-1-generic

Any additional info needed, just ask will be happy to provide.
