https://bugzilla.novell.com/show_bug.cgi?id=813018 https://bugzilla.novell.com/show_bug.cgi?id=813018#c0 Summary: Crash on insmod radeon (patch provided) Classification: openSUSE Product: openSUSE 12.3 Version: Final Platform: x86-64 OS/Version: openSUSE 12.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: munderl@tnt.uni-hannover.de QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0 In rare circumstances, insmod radeon can produce a division by zero. In my case this happens everytime on a modprobe radeon after module was unloaded before (rmmod radeon). A patch to this can be found here: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f6... Would be nice if it will be included in future kernel updates. Reproducible: Always Steps to Reproduce: 1. rmmod radeon 2. modprobe radeon 3. division by zero kernel dump -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Strange. It seems this patch is already included in openSUSE kernel 3.7.10-1.1.

https://bugzilla.novell.com/show_bug.cgi?id=813018 https://bugzilla.novell.com/show_bug.cgi?id=813018#c3 --- Comment #3 from Marco Munderloh 2013-04-02 19:19:37 UTC --- This is the initial module load. For the variables, see the patch above. disabled_rb_mask fc total_max_rb_num: 8 rendering_pipe_num: 4 req_rb_num: 2 This is the crashing load. disabled_rb_mask seems to be forced to 0xff through the patch above. However it does not prevent reg_rb_num to become zero, so pipe_rb_ratio = rendering_pipe_num / req_rb_num crashes. disabled_rb_mask ff total_max_rb_num: 8 rendering_pipe_num: 4 req_rb_num: 0 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In the crash case, disabled_rb_mask is 0xff before the patch and tmp is also 0xff, therefore disabled_rb_mask stays at 0xff. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I tried latest stable defautl kernel 3.9.4-1 and it still gives a kernel "divide error: 0000" at "evergreen_gpu_init" on the modprobe after rmmod. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
