Hi, I have a SiS 746FX based motherboard. Up untils 2.6.13-gentoo I got agp-support by modprobing the sis-agp module. With 2.6.13-gentoo the modprobe fails silently. The agpgart module is loaded, and no error is shown, but in dmesg the sis-output is missing and /proc/drivers/nvidia/agp/status says that AGP is disabled. modprobe sis-agp should at least do something, but lsmod and dmesg show nothing, and there is no error shown either. Reproducible: Always Steps to Reproduce: 1.emerge kernel 2.6.13-gentoo 2.configure for modular agpgart/sis-agp support 3.built the kernel, boot and modprobe sis-agp Actual Results: nothing. agpgart.ko gets rightfully loaded, and shows up in dmesg, sis-agp not. lsmod does not show sis-agp, rmmod sis-agp fails because of missing module in /proc/modules. Expected Results: I should see some sis-agp related output and AGP should work. OR it should fail with an error. lspci 0000:00:00.0 Host bridge: Silicon Integrated Systems [SiS] 746 Host (rev 02) 0000:00:01.0 PCI bridge: Silicon Integrated Systems [SiS] SG86C202 0000:00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS963 [MuTIOL Media IO] (rev 25) 0000:00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller 0000:00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] 0000:00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:03.2 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller 0000:00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 90) 0000:00:0a.0 SCSI storage controller: Adaptec AHA-2944UW / AIC-7884U (rev 01) 0000:00:0b.0 Multimedia video controller: Brooktree Corporation Bt848 Video Capture (rev 12) 0000:00:0c.0 Multimedia audio controller: Fortemedia, Inc Xwave QS3000A [FM801] (rev b2) 0000:00:0c.1 Input device controller: Fortemedia, Inc Xwave QS3000A [FM801 game port] (rev b2) 0000:00:0d.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10) 0000:01:00.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] (rev a1) 17180735.184000] Linux agpgart interface v0.101 (c) Dave Jones [17180738.624000] ACPI: PCI Interrupt 0000:01:00.0[A] -> GSI 16 (level, low) -> IRQ 21 [17180738.624000] NVRM: loading NVIDIA Linux x86 NVIDIA Kernel Module 1.0-7676 Fri Jul 29 12:58:54 PDT 2005 [17180748.820000] ACPI: PCI interrupt for device 0000:01:00.0 disabled [17180754.784000] ACPI: PCI Interrupt 0000:01:00.0[A] -> GSI 16 (level, low) -> IRQ 21 [17180754.784000] NVRM: loading NVIDIA Linux x86 NVIDIA Kernel Module 1.0-7676 Fri Jul 29 12:58:54 PDT 2005 energy ~ #

Hi, ok, I found it, it is not the kernel! good news everybody, it is modprobe. modprobe sis-agp --> agpgart is loaded, sis-agp not insmod /lib/modules/2.6.13-gentoo/kernel/drivers/char/agp/sis-agp.ko ---> sis-agp&agpgart are loaded, agp works. but why? I made a depmod -a after the first problems, and it solved not the problem. Plus I am using this hardware setup/kernel-config combination for a long time and this was the first time that this happened So I change it to minor - it is 2:45 in the morning and I panic'ed ;)
Hi, one more point: after sis-agp did not modprobe, I first rebooted, without changes, than build a vanilla kernel.org 2.6.13, which after the reboot did not modprobe sis-agp too. After that I rebooted into 2.6.13-gentoo again, did checked the logs, did a lot of modprobe than the insmod and bingo, it worked. My main problem is:
Please post the output of "modprobe -v sis-agp" and the messages which appear in dmesg after you run that.

Which version of module-init-tools is in use?
Hi, emerge -s: sys-apps/module-init-tools Latest version available: 3.2_pre7-r1 Latest version installed: 3.2_pre7-r1
Looks like a module-init-tools bug, apparently it's not even _trying_ to load sis-agp when you run "modprobe sis-agp"...
Hi, hmm, if it is a module-init-tool bug, should it not have shown itself with earlier kernels? Because AFAIR 2.6.12-X were working fine with the same module-init-tools version.
Hi, I have to correct mmyself - just installed 2.6.12-gentoo-r9 to make sure - and modprobe sis-agp does not work there too.
does it work with older module-init-tools ?
Hi, I tried module-init-tools 3.1-r1 and sis-agp fails there too.
if you have a minute, think you could take a look at this issue for us rusty ?
This seems very strange; I suspect the kernel is trying to load modules itself, confusing the issue. I suggest creating a simple script in /tmp/modprobe, like so: #! /bin/sh echo ARGS: "$@" >> /tmp/modprobe.log exec /sbin/modprobe "$@" Then chmod a+x /tmp/modprobe, and echo /tmp/modprobe > /proc/sys/kernel/modrpobe. Now, you'll get a message in /tmp/modprobe.log if the kernel is trying to load things. If you do a modprobe -v sis-agp, what happens now? Puzzled, Rusty.
Hi, I did and there was no modprobe.log in /tmp. when I did modprobe -v sis-agp If I do it I get this: modprobe -v sis-agp insmod /lib/modules/2.6.13-gentoo/kernel/drivers/char/agp/agpgart.ko but no /tmp/modprobe.log BUT when I start X, I have suddenly the modprobe.log, which has this: cat /tmp/modprobe.log ARGS: nvidia so at least it works - for nvidia&co but not for sis-agp
Hi, I just updated to 2.6.13-gentoo-r1 and upon reboot, sis-agp.ko was modprobed correctly.
Fails for me with 2.6.13-gentoo-r3,r2 (and vanilla 2.6.14-rc3), and "an indeterminate number of" previous gentoo kernels. Specific insmod works as listed in the other reports in this thread. Mobo is ugly. cheap K7S5A.
Stale bug. Reopen if you can reproduce this w/ current module-init-tools and uptodate kernels. Thanks.
I don't have the hardware anymore, so testing is impossible ... I am fine with closing it. If anybody still using sis-boards would have had hit this bug, he would have left a comment... so I am pretty sure, that this bug died a long time ago (and I completly forgot its existence).
