Hi,

After upgrading from hotplug-20020828 to hotplug-20030501, I have had some problems with loading modules.. First, loading radeon module gives me this:

Linux agpgart interface v0.100 (c) Dave Jones
[drm] Initialized radeon 1.8.0 20020828 on minor 0 [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held [drm:radeon_unlock] *ERROR* Process 3971 using kernel context 0

While with old hotplug version I get this:

Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected SiS 646 chipset
agpgart: Maximum main memory to use for agp memory: 438M
agpgart: AGP aperture is 64M @ 0xe8000000
[drm] Initialized radeon 1.8.0 20020828 on minor 0
agpgart: Found an AGP 2.0 compliant device.
agpgart: Putting AGP V2 device at 00:00.0 into 4x mode
agpgart: Putting AGP V2 device at 01:00.0 into 4x mode [drm] Loading R200 Microcode

Also some other modules don't load automatically when using the new hotplug version (e.g. alsa oss emulation). I am using devfs and module-init-tools-0.9.11a on Gentoo distribution. I went back to old version to have my system working ok again.

P.S. Please CC me any questions as I am not subscribed to the list.

Thanks, Sami

I'd suggest posting this to the linux-kernel mailing list, as that's a kernel driver change, nothing the hotplug scripts could have changed there :)

Does Gentoo patch the base hotplug scripts any?
What kind of modules do not load, pci ones? Do you need to add fields to the usermap files?

thanks,

Ok, I'll post there. I was also thinking that this is a bug on radeon driver, but it only appears when I use this newer hotplug release.

Yes it does. The small patches are here:

SIS900 driver for the network adapter did not load. The problem with alsa oss emulation module is that it loads but the entry /dev/dsp does not appear until I remove the module and modprobe again. This may also be kernel bug, but again only appears with the newer hotpug release. I have not added any fields to usermap files for these modules.

Thanks, Sami

Is this a pci driver issue? It looks like Gentoo patched things in the scripts to work a bit differently in that area.

If you change hotplug scripts this gets fixed? That's really wierd, as it seems to be a devfs issue more than a hotplug issue.

Sorry I don't have any more ideas.

Yes, it seems to be pci issue. This is a notebook with integrated SiS ethernet and sound chips.

Yes, only difference between working and non-working configuration is the version of hotplug.

Thanks for your replies, I'll try to tweak some things to find more info and check the gentoo patches, maybe I drop some parts of them.

BR, Sami
