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 at lists.freedesktop.org
ReportedBy: writemeanddie at hotmail.com
system 32 bit gentoo
video card ATI RS482 configured to share 128MB system RAM
kernel 2.6.38.4

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.
