View Full Version : Fedora 9 %1 Boot Hang Issue

23rd December 2008, 07:41 PM
Hello Community,

I am currently working on a project that uses the Fedora 9 distribution but I'm experiencing a fatal boot hang issue that occurs about 1% of the time when ACPI support is enabled (I need ACPI support). With quiet boot mode disabled here are the last 10 lines that appear before it hangs:

net_namespaace: 64 bytes
NET: Registered protocol family 16
ACPI: bus type pci registrered
PCI: PCI BIOS revision 2.10 entry at 0xff61a, last bus=1
PCI: Using configuration type 1
Settings up standard PCI resources
ACPI: Interpreter enbled
ACPI: (supports S0, S1, S3, S5)
ACPI: Using IOACPI for interrupt rounting
ACPI: PCI Root Bridge [PCI0] (0000:00)

When I say hang I mean a hard system hang, keyboard does not respond and system has to be powered down or reset button pressed.

My Questions:

What is the best way to debug this issue besides disabling quiet boot mode?
Is this a known issue on other target platforms?
Is there a work around to prevent this hang from occurring and still have ACPI enabled?

How I reproduce the issue:

Install Fedora 9 on target system via standard distribution install DVD (Fedora-9-i386-DVD)
Edit /etc/inittab by changing “id:x:initdefault” to “id:6:initdefault” (this makes the system reboot on startup)
Reboot system

Result: System will eventually hang (takes about 2 hours on my target system most of the time).

Your help will be greatly appreciated! Let me know if you need any additional info.

Why did you edit /etc/inittab to run init level 6 (reboot)? What was the point of that?

What you posted isn't really much help at all!

The point was to reboot the system on startup. Like I said your welcome to ask any questions. In the mean time I will take a look at the link you sent me, it looks promising.
