When I boot I sometimes get this error right as USB and PCI hotplugging is started.
(This took me a while to copy down so I replaced a lot of the debugging numbers with the # sign.)
| Code: | Starting USB and PCI hotplugging:

At this point all I could do was use Shift+Pageup to go up the screen and hit Ctrl+Alt+Delete to restart. As it reboots it gives another error related to the problem. I am unable to get to a VT or anything when this error occurs. This happens fairly regularly. Usually once it happens it will occur for two or three more boots and then boot fine. I am unable to find a log related to this error anywhere once I'm in the system.
These are the things I'd like to know:
* Is it possible my video card (radeon 8500) is going bad and causing this probe error?
* Why are these errors random?
* Is it possible I should disable some pci option or remove the radeonfb module from the kernel?
* Should I report this to kernel-dev?
* Is there a way I can log this? Maybe I need to enable extra logging features?
I am using gentoo-dev-sources-2.6.3-r1 as well as mm-sources-2.6.3-r4. All my radeon stuff (DRI,FrameBuffer,agpgart) is compiled as modules and I'm not explicitly loading any of it (though it seems hotplug finds it). I have been using these kernels for a while before the problem occured.
I have a gut feeling that my card may be going bad, but if you have any insight into the problem it would be appriciated.

I have the same error. A kernel oops during hotplug start.
It seems (but I'm not sure) related to the hotplug trying to load a module that is built into the kernel (scsi controller in my case).
It happens with 2.6.4-r1, 2.6.5-r1, 2.6.6-rc2 from kernel.org
For the moment I disabled hotplug, but I think it's not the right solution.
[update]
I still have the same error with 2.6.6-rc3, vanilla 2.6.6 and 2.6.6-mm
Is it possible that so few people is having this problem? |
