  Running
  Description:	Ubuntu 10.04 LTS
  Release:	10.04
  Linux jim-nb 2.6.32-24-generic #38~pre201007021000-Ubuntu SMP Sun Jul 4 06:49:54 UTC 2010 i686 GNU/Linux
  But problem seen on all kernels tried.
  
  Boot process hangs for ~7 minutes, then machine starts.  Booting with
  init=/bin/bash and running "hdparm -t /dev/sda5" (sda5 is my ubuntu fs)
  gives ~500kB/sec.  Completing the upstart process brings disk up to ~40
  MB/sec.
  
  When " bootchart" is installed machine boots in 23 seconds!  Resume from
  hibernate works.  Investigation has shown that a compiled C program with
  an infinite loop, when run in the background from init-top in the
  intramfs will also cure the slow boot.  The C-program saturates one of
  the two processors of the Atom N450 (~100% CPU1).  It appears that
  bootchart works its magic by simply saturating one CPU.  After boot,
  running the inifinite loop program brings disk performance (as reported
  by hdparm) up from 40 MB/sec to 70 MB/sec.
  
  Adding highres=off nohz=off to the kernel command line cures slow disk
  problem but machine runs hot with lower battery life.  Adding nohpet to
  the kernel command line also cures the slow boot but not the resume from
  suspend.
  
  I suspect that the problem lies with ahci.ko or libata.  Changing the
  BIOS disk parameter from ahci to compatibility also cures the problem...
  but screws up the existing Windows partition.
  
  Tried the linux-image-2.6.35-020635rc3-generic_2.6.35-020635rc3_i386.deb
  kernel.  It acts the same.
