Description Per Toft 2007-07-05 07:07:32 UTC
Most recent kernel where this bug did not occur: 2.6.22-rc7
Distribution: Ubuntu gutsy (developnent release)
Hardware Environment: AMD Turion X2, NForce C51
Software Environment: 2.6.22-rc7 x86_64 AND x86
Problem Description:
System hangs on boot when "setting up timer" or "loading additional drivers" if not nolpic or pci=noacpi is added.
If nolpci or pci=noacpi is added the system can boot, but the IRQs for the second PCI express buss are note assigned.

Any suggestions?
Comment 1 Len Brown 2007-07-11 19:12:42 UTC
The most important thing here is the boot hang, so lets focus on that...

The fact that "nolapic" makes the problem go away suggests
that the LAPIC timer is being used for clock ticks, yet
the LAPIC timer isn't working.

This may be an AMD issue in C-states, so please test
if it goes away if you boot with "idle=poll"

If that isn't the problem, then it may be related to
a different clock source, such as the PIT, and various
Nvidia chipsets have this screwed up in different ways,
try both acpi_use_timer_override and then acpi_skip_timer_override
to see if that is related to the problem.

I'm not going to worry about how your device interrupts
are not working with pci=noacpi, as that is by definition
a non ACPI problem:-)

finally, this bug is filed against 2.6.22-rc7, but it also states
that 2.6.22-rc7 was the last known working version.  Please clarify
if 2.6.22 is working or failing, and if any recent version before that
is working w/o any cmdline workarounds.
Comment 2 Len Brown 2007-07-11 19:16:50 UTC
also, please attach the output from acpidump,
and the complete dmesg from a successful boot with nolapic,
or with whatever of the params above that work.

/proc/interrupts with single pci=noacpi kernel options
Comment 7 Per Toft 2007-07-12 06:57:29 UTC
Kernel: 2.6.22-7-generic. I will try the latest kernel later today...
I have tried to boot with the different configurations. I used single user mode to ensure no further problems in all cases:

single idle=poll - System freeze when: "Loading hardware drivers" \n "error receiving uevent message: No buffer space available"
I have iterated this step five times with the same result.
 
single acpi_use_timer_override - System freeze when: "Setting the sysem clock"
Iterated five times. All results the same...

single acpi_skip_timer_override - System freeze when: "Setting the sysem clock"
Iterated five times. All results the same...

single nolacpi - System boots in single user mode.
Iterated five times. One success and four other random freezes.
It might be coincident that it worked previously with this option.

single pci=noacpi - Boots successfully, but with edge triggered interrupts and rare random lockups.

I have attached a dmesg and the output from /proc/interrupts

Hope this will help.

With regards
M.Sc.EE. Per Toft

These other bug threads may help.

http://bugzilla.kernel.org/show_bug.cgi?id=8219

As of gentoo's 2.6.22-gentoo-r1 #1 SMP compiled Fri Jul 20 2007, I still require acpi_use_timer_override, however all the details are in the later thread.
Comment 9 Fu Michael 2007-10-10 01:27:38 UTC
(In reply to comment #7)
> single nolacpi - System boots in single user mode.
         ^^^^^^^
Just to make sure it's just a typo instead really used as kernel parameter. Correct parameter should be nolapic, instead of nolacpi...

> Iterated five times. One success and four other random freezes.
> It might be coincident that it worked previously with this option.

it looks like not a local apic issue from your description...could you please try the kenrel parameter acpi=noirq. ( not use pci=noacpi )

assign it to Len.  
Comment 10 Per Toft 2007-10-12 01:10:11 UTC
Correct!
It should be:
single nolapic 

Ill try later to boot with apic=noirq and see the results
Comment 11 Fu Michael 2007-11-12 18:37:05 UTC
Per Toft,

any update of the test result of using "acpi=noirq".

note: NOT "apic=noirq"...
Comment 12 Fu Michael 2007-11-18 21:49:58 UTC
a dup of bug# 8219? could you please try to boot with kernel parameter acpi_use_timer_override
Comment 13 ykzhao 2007-11-18 23:58:15 UTC
It will be more useful if boot option(apic=debug) is added besides the option in comment #11 and #12.
Thanks.

Comment 16 Len Brown 2007-12-28 21:55:28 UTC
no response since 2007-10-12, please re-open if this is still an issue
with the latest upstream kernel.org kernel.
