** Description changed:
+ Given the nature of this issue, it seems appropriate to provide a
+ release note regarding this issue. Subscribing ubuntu-release-notes to
+ this bug and proposing the following release note text:
+
+ During the Maverick development cycle, support for the intel_idle driver was
included in the Maverick kernel. The intent of intel_idle is to allow Linux to
take better advantage of Intel hardware and make Linux more immune to ACPI BIOS
bugs and shorcomings of the ACPI implementation itself. This unfortunately
appears to have an adverse affect on Lenovo S10-3 systems (Intel Atom N450
processor) rendering them incapable of booting. There currently exists a
workaround. If one passes "intel_idle.max_cstate=0" as a kernel paremeter at
boot, this will disable intel_idle and allow the S10-3 to successfully boot.

+ =====

I updated Ubuntu 10.04 netbook edition to 10.10 beta.
The system hangs with 2.6.35-19 kernel at an early stage. There are no logs
generated. The last few messages on the console are:
[ 2.692654] USB Mass storage support registered.
[ 2.693649] scsi2 : ahci
... scsi3 : ahci
... scsi4 : ahci
... ata1 : SATA max UDMA/133 abar ....irq 43
....ata2 : - as above -
... ata3: DUMMY
... ata4: DUMMY
[ 2.716847 Btrfs loaded
Hangs after that. Hard reset is needed.
However, it boots with the 2.6.32-24 kernel of 10.04.
I tried with the Kubuntu 10.10 desktop edition as well. Could not
install it as the system hung at an early stage.
In case it helps, the 2.6.35 kernel with Arch Linux boots fine.
