ACPI: PCI Interrupt on boot
 

Something happened, and now everytime I try to boot linux on my laptop it hangs and shows:

I'm running a IBM Thinkpad T22. everything worked fine, and I didn't install anything.. can someone help me out? this happened a few times in the past, but eventualy the error just went away, now its back again :(

The system is stalling here on boot?
What distro?
What kernel version?
Have you updated the kernel before the error?

I'm using slackware. yup it freezes and that's it .. no I haven't updated my kernel

I would guess there might be a hardware issue arising. That portion of the boot is still in the kernel loading portion. Running of any other scripts or mounting the drives have not happened yet. My guess would have been a kernel bug but since the kernel has not changed then I would narrow it down to a hardware issue. Being a laptop it would be hard to figure out.

Have you tried using a Live CD like knoppix or Kubuntu? See if they boot and see if they can mount the drive partitions. If the Live CD boots then check the log files to see if any erors have been occurring. Errors like a drive errors.

That is about all I know to do.

thx. I've actualy been looking in the hardware direction. apparently there's either something wrong with my PCI bus manager, or somethings up with my network card, because if I disconnect it, there laptop runs without any problems..

is there a way to disable my network card running on boot? and then to enable it after login?

You are talking about the internal wired ethernet nic correct?
And you disable it through the Bios I assume?

If so not sure of anyway to reenable a disable bios setting from within linux.

Maybe in the bios if there is an option like Plug and Play (yes or no) make it no. Or if you can assign one of the IRQ to Legacy ISA like IRQ 11. This will only allow a single PCI device on that IRQ. Forcing other devices to other IRQ's that pci can share.

Only other thought is recompile the kernel and change the PCI access mode to say Direct. Possible Bios option and the other two are MMConfig and Any. Usually I believe the default is any. Since laptops are properitory in nature it may have an issue deciding which one to really use.

Have you check out this site to see others have had similiar issue like this? http://www.linux-laptop.net/

recompiling the kernel wouldn't help at all. i've tried using different distros and kernels with no luck at all.

yes I removed the internal network chip.

this IBM bios is by far the most stupidest bios ever .. I can't disable plug n play, I can't reasign the IRQ's, only enable or disable them (which doesn't help, tried that) no way to change anything.. I would hope that there is a way to disable such things on boot ...

When you mention other distros and kernels, most use the default kernel.org structure. Have tried the items I mentioned about the PCI Access Mode and possible making the network module part of the kernel instead. It may force things to load in diffferent order.

As far as disable it would require rewritting of the bios cmos to be able to control that. But not sure how one would be able to reintialize the nic later. A topic well beyound me. Not sure where to start on this. Other than that I have no other thoughts.
Good luck.

Brian

ok.. how about just disabling it?

Not sure if you can disable it. The PCI seems to be finding the devices. So if you blacklist the module for the nic in your udev or hotplug that would not do it since it is loaded later on. Out of ideas other than sending it in for a repair if it is hardware related. Maybe still under warranty.

I have a feeling that it's probably a bug or linux doesn't fully support my laptop.

The waranty is long gone .. This laptop is like 4-5years old. Still runs well though

I am having the exact same problem, accept that my computer continues booting after hanging for a good 3-5 minutes. Have you tried waiting this long to see if it continues booting afterwards?

I installed Ubuntu 6.10 today - the live (install) CD did not hang in this way.
