Swâmi Petaramesh, thank you for reporting this and helping make Ubuntu
better. This bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please provide information following
https://wiki.ubuntu.com/DebuggingKernelBoot ? As well, can you try with
the latest development release of Ubuntu? ISO CD images are available
from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the
development release from a Terminal
(Applications->Accessories->Terminal). It will automatically gather and
attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would
be great. It will allow additional upstream developers to examine the
issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once
you've tested the upstream kernel, please remove the 'needs-upstream-
testing' tag. This can be done by clicking on the yellow pencil icon
next to the tag located at the bottom of the bug description and
deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not
boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.

** Tags added: needs-upstream-testing resume suspend

** Tags added: oneiric

** Summary changed:

- [Maverick beta] [kernel] HD may freeze during system boot or resume
+ HD may freeze during system boot

** Description changed:

  - This error didn't exist on same system using Lucid and previous Ubuntu
  releases / kernels
  
  - Although system is rather old, HD is rather new (less than 200 hours
  runtime) and has perfect SMART values.
  
  Symptoms:
  
- * System will OFTEN hang when resuming from suspend and SOMETIMES when
- cold-booting (Plymouth being displayed).
+ * System will SOMETIMES when cold-booting (Plymouth being displayed).
  
  * When hanged, HD LED stays steadily lit, but HD isn't audibly
  "scratching".
  
- * When hanged during resume, it can be noticed that system isn't
- completely "dead", keyboard still responding and allowing to shift from
- a virtual console to another, but any attempt to access HD will
- definitely freeze system.
- 
- * Once system succeeds booting or resuming without hanging, it then is
- perfectly stable.
- 
+ * Once system succeeds booting it then is perfectly stable.
