--- Comment #12 from Bjorn Helgaas <[email protected]> 2009-07-10 17:57:58 --- Created an attachment (id=22302) --> (http://bugzilla.kernel.org/attachment.cgi?id=22302) print names of unloaded modules Thanks for doing all this testing. Using CONFIG_DRM_I915_KMS=y might be another workaround, but we still need to fix the hangs and oopses that happen when it's disabled. Hangs are hard to debug, so the most interesting thing to me is the oops that happens with the older button.c -- that gives us real data to work with. Both oopses show an invalid IP, which may be the result of memory corruption. Can you set the following config options: CONFIG_DEBUG_PAGEALLOC=y CONFIG_PAGE_POISONING=y CONFIG_FRAME_POINTER=y CONFIG_DEBUG_NOTIFIERS=y CONFIG_MODULE_UNLOAD=n (note this one is *disabled*, not enabled) Before closing the lid, please also collect /proc/modules and /proc/kallsyms, e.g., # cat /proc/modules > modules # cat /proc/kallsyms > kallsyms If the problem goes away when CONFIG_MODULE_UNLOAD=n, that's a good clue that some module's unload is buggy. So if you can't reproduce the oops with CONFIG_MODULE_UNLOAD=n, turn it back on and try it again with this patch, and maybe we can get a list of modules to look at. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
