Most recent kernel where this bug did not occur: cannot say, I am trying to confirm whether bug #2913 still exists. Distribution: Gentoo Hardware Environment: ASUS L3C/S laptop, P4, Radeon 7500M Software Environment: vanilla 2.6.22.6 Problem Description: I went to singleuser mode, but my system picked up the modules so they got loaded and placed me into singleuser. I went to unload all the modules, in which I succeeded except two modules: agpgart and intel_agp. agpgart should be unused but it claims it is being used. How can I find who is using it? I Steps to reproduce:
Created attachment 12845 [details] cannot unload agpgart nor intel_agp
Created attachment 12846 [details] forcing agpgart unload causes oops BTW, my HW setup is normally detected as: Linux agpgart interface v0.102 (c) Dave Jones agpgart: Detected an Intel 845G Chipset. agpgart: AGP aperture is 256M @ 0xe0000000 [drm] Initialized drm 1.1.0 20060810 [drm] Initialized radeon 1.27.0 20060524 on minor 0 ... agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode [drm] Setting GART location based on new memory map [drm] writeback test succeeded in 2 usecs
I think there were relevant fixes made by Dave Jones since. Martin, have you tried using recent kernel, is the problem still there?
Ping... I am tending to close this bug soon, so "silence is consent" :)
I have unloaded all modules except these two by rmmod command: Module Size Used by intel_agp 23316 1 agpgart 31280 1 intel_agp # I tried to force removal of agpgart but it said something about temporarily disabling of the device/module but it remained in the module list and nothing got apparently logged by syslog. I had to force removal of intel_agp and only then I have succeeded in removing agpgart (without forcing). And, no kernel crash (2.6.24.2).
Created attachment 15135 [details] "ps -ef" and "lsof" outputs I have no idea why I had to force unloading of intel_agp. I don't think it was opened.
Created attachment 15136 [details] /proc/config from running kernel 2.6.24.2
Closing out old stale bugs. If this in error please re-open
