[Nouveau] [Bug 23712] New: NVA0 KMS: kernel NULL pointer dereference
http://bugs.freedesktop.org/show_bug.cgi?id=23712 Summary: NVA0 KMS: kernel NULL pointer dereference Product: xorg Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy: peter.henriksson at gmail.com QAContact: xorg-team at lists.x.org Created an attachment (id=29219) --> (http://bugs.freedesktop.org/attachment.cgi?id=29219) kernel log I have been getting this NULL pointer dereference since drm-next was merged to nouvuea/linux-2.6 master on August 21. The card is a GeForce GTX 275 (NVA0) The dereference does not happen in the following circumstances. 1. kernel has CONFIG_DEBUG_INFO=y 2. booting with kms disabled and then reloading the module with modeset=1 What other information should I provide to help figure this out? bisecting is difficult due to the drm-next merge. The attached trace is with current master (e02aed2) -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

[Nouveau] [Bug 23712] NVA0 KMS: kernel NULL pointer dereference
http://bugs.freedesktop.org/show_bug.cgi?id=23712 --- Comment #4 from Peter Henriksson <peter.henriksson at gmail.com> 2009-09-23 00:06:11 PST --- It might be a good idea to write things down here and not just mention it on irc. I have tested for this bug with a few different cards I have access to with the following results. NVA0 (GTX 275) Crash NV92 (8800 GTS) Crash NV92 (9800 GT) Crash NV4B (7600 GT) Works So it seems only NV50 is affected. And there is some suspicion that this is only in combination with a 32bit kernel. Also, bugs #23847 and #29593 is probably the same as this one. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
