[Bug 100110] Re: 18 seconds ACPI delay while booting due to DSDT

[Ptitphysik]

** Description changed:

  [This bug in the past has been worked round by fixing the daft sleeps in
  the ACPI DSDT and using the user DSDT support to replace it.  In Karmic
  this is nolonger available due to upstream concerns about dammage to
  hardware.  The norm is to try and quirk round these sorts of ACPI errors
  in the kernel.  The work on karmic is related to detecting and avoiding
  those when using the existing borked DSDT.]
  
  Mainly on Fujitsu laptops.
  Exist on Karmic.
+ Exist on Lucid.
  Win Vista does not have the same problem.
  The solution in comment 10 works.
  
  Every time I boot Ubuntu on my notebook, the boot procedure is delayed by 18 seconds. After selecting the kernel in the GRUB menu, the screen shows "Starting up", and then for 18 seconds absolutely nothing happens: no CPU activity, no disk activity, just waiting. After the delay, the boot procedure continues without errors or warnings.
  When I reported this behavior to the ubuntuusers.de forum, it was confirmed by another user who uses the the same notebook model.
  
  This seems to be a Linux Kernel problem because I have no delay booting
  Vista which is also installed on this notebook.
  
  I'm using Kubuntu 7.04 on a FSJ AMILO Xi 1554 notebook (Core 2 Duo
  T7200, 2 GB RAM, 17", ATI Mobility Radeon X1900). The behavior was
  always the same for all kernels I've tested: Generic 32-bit kernels from
  2.6.20-9 to 2.6.20-13.
  
  bootchart tells me that before the delay "init", "khelper" und "kthread"
  are started in short succession, then the 18 seconds delay, and the
  "kseriod", "pdflush", "kswapd0", "aio/0" and "aio/1" are started.
  
  The boot log gives me the impression that this is an ACPI problem:
