[Bug 38839] Fails to boot on a centrino laptop

[Tero Karvinen]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Booting freezes on "Uncompressing Linux... Ok, booting the kernel. ".

To reproduce:
On Acer Travelmate 3004WTMi (Intel Centrino), with Dapper Flight 6 i386 Install CD-ROM
1) Boot from CD
2) Choose "Install to hard disk"

What happens:
The text "Uncompressing Linux... Ok, booting the kernel. " is printed on the screen. After that, complete freeze: Caps lock does not change
lights, alt-ctrl-del does nothing, a quick click on power
button does nothing. Must shut down computer by pressing
power button for 10 s.

What should happen:
Computer should boot normally. 

To bypass:
1) Booted from CD
2) Move cursor to "Install to hard disk" 
3) "F6 Other Options": added "noapic"
What happens:
Computer booted past the "booting the kernel. "
(3004WTMi also needs "irqpool" option to use network and DVD-drive).

The computer is Acer Travelmate 3000 3004WTMi. CPU is Intel Centrino, Intel(R) Pentium(R) M processor 2.00GHz, version 6.13.8. BIOS is Acer  3B07 (06/08/05), has (among others) capability "biosbootspecification". Motherboard is Hummingbird. I used md5sum to check the CDROM iso before burning, and "verify CD" in installer to check that CDROM is good. More on my setup and tests:
