Summary: segfault in crackberg xscreensaver on ATI RS482 in mesa git running kms & gallium Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: writemeanddie@hotmail.com
system 32 bit gentoo video card ATI RS482 configured to share 128MB system RAM kernel 2.6.38.4 xorg-server 1.10.1 mesa git commit 37058c3497850f452bdaf70a5dda07ee4840b6b9 May 4 2011 xf86-video-ati git commit 62a4cd180fe884dca24586d453395472516e6496 May 4, 2011 mesa compile flags: classic egl gallium llvm nptl openvg shared-dricore video_cards_r300 video_cards_radeon xscreensaver 5.12
When running the xscreensaver 'crackberg' on mesa from git the screen freezes for 20-60 seconds (I think memory is filling up and swapping out RAM) and then the program exits with a segfault. The message in /var/log/kern.log is kernel: crackberg[30926]: segfault at b5a30000 ip b653b2c1 sp bf943e30 error 4. If I downgrade to mesa 7.10.2-r1 the screensaver works as expected. If I run with ums the screensaver works as expected. Other screensavers are affected as well, I can compile a list if necessary.
Any other logs or info that I can collect is no problem.
