[Bug 589853] Re: Ubuntu 10.04 LTS AMD64 hangs boot

[RobinhoLemos]

** Description changed:

  The boot process stop with this lines:
  
  ACPI: Power Button [PWRB]
  processor LNXCPU:00: registered as cooling_device0
  processor LNXCPU:01: registered as cooling_device1
  processor LNXCPU:02: registered as cooling_device2
  processor LNXCPU:03: registered as cooling_device3
  Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled
  serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
  00:0a: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
  ACPI: PCI Interrput Link [LNKA] enabled at IRQ 19
  serial 0000:01:06.0: PCI INT A -> Link[LNKA] -> GSI 19 (level, low) -> IRQ 19
  
  Ubuntu 10.04 LTS i386 works fine, but the AMD64 boot hangs in this message.
  I can't post the info about the AMD64, because any cheat parameters don't work.
  
  Tried: acpi=off, acpi=ht, irqpoll, pci=nomsi, noapic, nolapic,
  acpi=force
  
  Already tried memtest. No errors in memory.
  
  Nothing solved, and I don't have response from keyboard. Only a blinking
  cursor. I use a Microsoft Wireless Desktop 2000 as Mouse and Keyboard.
  I've put a PS/2 Keyboard, but no success.
  
  Tried to change parameters inside the BIOS disabling Serial,
  enabling/disabling Virtualization, Cool'n'Quiet, ACPI, APIC, APM,
  choosing Default Settings from BIOS. No success too.
  
  My specs:
  * AMD Athlon II X4 630 2.8GHz
  * 4GB DDR2-800
  * ASUS M2N68-AM SE2
  * XFX Radeon HD4650 1GB DDR2
  
  Windows Vista & 7 64bits works fine.
  
  Attachments are coming. I'm gonna get system info in Ubuntu x86. If I
  can post a photo and a video demonstrating the problem, i'll post here.
  Thanks.

+ EDIT: Solved by looking for device 01:06.0 on Everest in Windows. It was
+ my SM56 modem. I removed, and it works like a charm! Sorry for any
+ trouble. This thread can be closed.
